I had a very nice stay in this flat. Grégoire's place has good access to the city centre and is just in the heart of Malasana, an area where you can find many alternative bars and cafés.
The flat in general is very spacious and comfortable. You have everything you need. The room itself is comfy as well. Living there was quite a sweet ‚flat-sharing’-experience, that reminded me of my study time and the lively atmosphere in my former flats when e.g. friends slept over in the living room. Grégoire and his flatmates were very cordial, talkative and easy going. I recommend it!
