We spent four nights in Beatrice's flat and can highly recommend it. It is a real Airbnb flat, as was the original idea - normally inhabited and just available when Beatrice herself is not there. If you are looking for a sterile holiday flat, this is not the place for you.
The location is great, not a particularly posh neighbourhood, but a very lively and popular one. Nevertheless, the flat is very quiet. With three metro lines right outside the door, you can get everywhere quickly. The surrounding area offers lots of restaurants and snack bars. This meant we always had dinner in walking distance. During the day, it is wonderful to buy fresh food (fruit and vegetables, fish and meat, baguette and of course cheese).
