Rooms are amazingly large and impressive. Spotless and comfortable. Highly recommended although potentially rather expensive compared to other properties.

The only hiccup to this property is that access to the Spa (eg swimming pool) is NOT included. A pass for 3 hours can be bought and it is not cheap. Reception accepted that Booking.com mobile app does not state this in their small print and it is through the app that I booked this property. The property must be fully transparent as to this additional charge because it causes significant disappointment.

1. Rooms 2. Gym 3. Cleaning staff - very welcoming 4. In room dining - very nice food

79 leva - €40 to use the swimming pool 35 leva - €17.5 for child any age to swim This is insult pricing. The Hyatt is free to use pool and spa.

nice view and location. stylish design. always a pleasure to stay at Millennium.

staff needs additional training. they behave like being at home, chatting or looking at mobiles when guests are around, no help when offloading luggage in from if the entrance. nothing major in fact but this makes the difference between real 5 star and wannabe 5 star.

rooms were very large, nice bathrooms. lobby was nice. breakfast was good. Simeon at reception who we met on our last day was great. Most staff were friendly and helpful. Parking was available - tho at an additional cost of 20 euros. Loved the blowdryer that was in the room. Nice bathrobes.

5 star hotel. - maybe for Bulgaria. No one greeted us when we arrived. No bellboy to help with bags. Check in was just ok. Had asked for a high floor but was told there was an extra charge for that. After getting our keys we were not told where the elevators were. No one showed us to our rooms, had no idea that curtains were on an automatic switch. no paper, no pen, nothing. Spa was an extra 40 euros for 3 hours!!!! that was ridiculous! Small details - but that is what sets a 5 star hotel apart. I would stay here again - just know you will have to lower your expectations.

Very nice location, clean, luxourious and huge rooms. Panoramic views are fenomenal, experience you must see.

Not much friendly and polite staff. We run into some arrogant and very rude members, expecially at the bar. Also, the bartender tried to trick us with bill and giving back money.

Some staff shifts are really sweet and very accommodating. The rooms are very clean and equiped with updated technologies and facilities. Breakfast is really good and has a good variety of food to accommodate all type of diets.

The check out was not the most plesant experience. I had amazing check-in and check-out eperience in the past and I am sure was just an episode. The ladies was almost bothered that I wads checking out at 04am and I had to ask for the invoice which was printed and passed over, the invoice was not the full stay invoice but only the lunch invoice that I asked the restaurant to charge it on the room.

We liked everything about the hotel and our stay. The ambiance was grand and elegant. True to their claim, I believe this hotel has the most spacious rooms in Europe for the price we paid for it. Our tour of Sophia and Bulgaria was part of a holiday tour of Europe. The team of staff was very kind and accommodating. They guided us to the best food, entertainment, and sightseeing choices. They helped us with all arrangements for private tours. The food in the restaurants was delicious and reasonably priced. The overall experience of our stay was thoroughly enjoyable. I would highly recommend this place to anyone.

wonderful rooms, clean and very spacious with attention to details and high quality materials

the pool isn’t available for kids under 16 which was disappointing

The hotel is very clean, beautifully decorated and veeery spacious indeed! What we enjoyed most was the service we got, especially from Georgi at reception, Petar who served us in the ball room, and the housekeeper, all of whom were lovely! Georgi went above and beyond to make sure our stay is off to a good start, he considered what room to give us in order for us to stay near our friends, and he demonstrated a very high level of professionalism! Pepi who served our meal and drinks at our special event in the ball room was also very attentive, he made sure our glasses were always full, remembered our drinks orders immediately, and didn't even flinch at our drunken ramblings towards the end of the night! I didn't take the housekeeper's name, but she also offered 5 star service. The bed was VERY comfortable, the hotel offered a variery of pillows, and high quality linen. The bathroom was beautiful and had both a huge bath and a spacious shower cabin. The room is well equiped with a tv, nespresso machine and a hairdryer. The food in 888 was fantastic, we've been to Ozone many times before, and are looking forward to it reopening after the renovation! I would definitely stay there again

Initially the reception team adviced that early check incurs extra charge of €10 per hour, which is odd, never have i been asked to pay extra for an extra hour or two. Thankfully, the brilliant reception team applied understanding, thus making up for the odd policy. The staff at the SPA centre were a bit misorganised, but thanks to the manager everything was sorted quickly, she was very professional.

The people at the front desk were very helpful and manage to fulfill all my requests. The housekeeping was also very friendly and always made sure that I have all I need in the room. They even provided me with additional complimentary water and coffee capsules as I was workign from the room. The gym in the hotel is an actual gym where also local go. This meant that the gym is very well equipped and there are also trainers available for answering questions. The internet connection was perfect for working from the hotel and I never had issues, which is surprising, taking into account that I was using only the WiFi connection. The bed is extremely comfortable and very speciouse. The location of the hotel is also lovely - very close to Sofia city center, which means that a lot of the good places to go out are within a walking distance. The view is amazing: I booked a regula room and was placed on an upper floor. The view over the city is beautiful.

There are very few points of improvement. The TV in the room is using a standard hotel TV system, which means and it cannot se used as a smart TV for streaming services, which is a shame. The wardrobe is small, so for longer stays it becomes a bit inconvenient. It would have been good to provide long-term-stay guests with a discount for the wellness center, as the wellness of the hotel is known to be one of the best in Sofia. This way the hotel can make their guests feel even more special.
