That the hotel is new makes it nice. It is near the Bio Campus convenient if you have business there, near the motorway but not right next to it, not too far from the city center if you have a car, but you can also take a bus to the u-bahn or walk 30mins through a beautiful forest to get to the u-bahn stop. The forest and the meadows around Martinsreid are great for runners. The hotel caters for vegan & gluten free diets. It is possible to sleep with the window open which is nice in summer. The rooms were nice & clean.

If you need to work from the hotel room, it has only a small table, so not so convenient. Also it's difficult to find space for more than one suitcase in the room.

This is a new and stylish hotel. The staff were friendly and helpful, and the breakfast rivalled 5-star hotels I have stayed in in the past. In my key areas of hotel quality: beds, pillows, towels and hot water - 10/10. Difficult to think how Grefis could have been better, especially at the price paid.

Very difficult to think of anything.

The food was fantastic and the rooms were set up very nicely.

I did not see that Children under 18 are not allowed in the pool. It was disappointing for us but the hotel staff really did all that they could to help our stay to be as enjoyable as possible.

A superb hotel. Modern, clean, comfortable, professional. Everything worked exactly as you want it to. The staff could not have been more helpful. The restaurant is absolutely top notch. I can’t recommend this hotel enough!!!

Everything was clean, the food was great and the beds were really comfy. Also the design of the hotel was nice!!

Everything

Friendly staff, lovely breakfast, comfortable room. There is a bus stop right outside. Takes a bit extra to get into the city vs staying somewhere on a train line but wasn’t too bad.

The shower smelt a bit off. And you had to open the door inwards to get in it which was weird. The shower also had a choice between rain head or high pressure washer at nipple level. Neither are a good options for a woman on a non hair washing day. Also the screen mirroring on the tv didn’t work.

- Modern, overall well-designed rooms (had a junior suite) - Beds, Couch with Pillows, Table & Mini Kitchen well designed in itself (however... see below) - Comfortable beds, excellent breakfast for this hotel class, nice rooftop bar with small pool, huge gym - Lots of free street parking around (the hotel parking was EUR 19 per night... rather steep for this location)

- Electric window blinds poorly designed - leave space at bottom, so with morning sun too much light coming in...would be easy to fix for hotel (or maybe just our room, 244 ?) - Safe too small for iPad / Laptop - that is a NO-GO today - No real wardrobe - Very little space in bathroom to place toiletries - there is a drawer shelf below washbassin, but not super-practical

Breakfast is excellent!!! Not just have varieties but also several delicate options. Very good!!! The hotel also have a restaurant, at the day that we are tired and this is the best choice to have your dinner. It also have a locker room. We arrived earlier in the morning, we locked our luggage in the locker room and then have fun in downtown area, check-in at night when we are back to the hotel.

We'll need to take a bus to the train station then to goto the downtown. But it is managable.

great facilities, comfortable rooms, good services, convenient parking.
