The cleanliness of the rooms, the perfection of the room services.

Nothing

The room was comfortable. Furnitures and wardrobes are very new and technological. Charging systems just near the bed well thought and designed. Bathroom can just be defined as perfect. The toilet is useful for all nationalities and its electronic. Bathroom amenities are fully in place. Breakfast has variety choice of options.

Room air condition system was not working properly. The price/benefit is quite high. Last minute compulsoey discretion fee apply on the invoice was not kind and not necessary. All visitors who stay on this hotel are well experienced and aware the proprieties. Incase they would like to share, they could share tip but not on that way. My room view was blind, looking into inside of the hotel hole. For that price that view was not fair.

Bear in mind that of the £930 cost for the night, A large chunk of that is VAT! Everything was just perfect. The service is exceptional but discreet. The staff are clearly highly trained. What I particularly liked is that they were polite but not overly deferential. They quickly knew when to have a laugh or a bit of banter. You are paying for the quality of the entire experience. The staff, the beautiful building, the location.

Nothing.

I like the location, excellent service, lovely staff. A very special thanks to Miss Lina and her colleague Mr…. from the reception for her wonderful reception and kindness, as we arrived at the hotel early before chek-in time and we were tired from the trip. So, she gave us free breakfast for the first day until the rooms were ready, and she also gave us early check-in to the rooms. Also special thanks to the great hotel guard for his service, kindness and smily face.

Ive stayed in lots of high end hotels in London and around the world. For service, the Mandarin Hyde Park was probably the best I've ever experienced, roads of staff on hand to help with anything, very discreet, calm and relaxed atmosphere. Excellent location, right in middle of Knightsbridge, amazing views of Hyde Park on the doorstep over breakfast. 1 minute from the tube which takes you all over London. Highly recommend

It's a shame the sauna, steam room, Jacuzzi can't be shared. As a couple it seemed odd to go to sauna separately or sit in male / female only Jacuzzi when you partner was in a different room. So we ended up not using those facilities

The hotel is stunning, the staff are beyond friendly and the facilities are amazing. The staff were very welcoming, attentive and nothing was too much trouble. The hotel and its facilities was immaculate. We had massages whilst there and they were out of this world. We were lucky enough to eat at Dinner after the receptionist organised a reservation (at very short notice) and the food was divine whilst the service was second to none. Overall we had an amazing stay and hope to return in the future.

The hotel offered healthy meals for breakfast. All meals are delicious and healthy. The furniture is in good condition with high-quality clean. The staff is friendly and helpful. The room is spacious and beautiful.

the time for check-in procedure was quite long. We had to stand when we was checking in. Many five-star hotels or resorts do not require clients to stand to check in, just take a seat in the waiting area.

excellent location, service, food, facilities (gym)

some small things could be improved : eg bathroom mirror did not have demister, drinking water by pool was warm, no bottles or cups for water in gym

It is a beautiful hotel. The room was clean and very comfortable. The location is excellent and close to Harrods and a tube station. The staff and doormen were friendly and helpful. We were provided with complementary champagne and a cake was provided for my husband's birthday.

None

Breakfast was great, our children and grandchildren met us and we had lovey time. The location is perfect for Knightsbridge and Mayfair. All the staff were extremely polite and very friendly.

Maybe next time we will have room overlooking the park, the noise from the sirens was deafening
