Whilst clearly the host is fantastic, the location is impeccable and the amenities, such as kitchen, laundry, bathroom are great, there are some important remarks. The flat being underground is not a problem at all, though no light. The main issue is that the bedroom gives on the street, and it s very loud. If you come with proper earplugs you will be fine. Otherwise be ready to have a short sleep as the window is very thin so one can hear everything (people, cars, even the subway). For the rest, on the improvements shared with the host, is the internet. Basically signal is almost inexistent (am sure she will fix this). Finally, well the door of the room is a shade window rolling glass. Now that did not bother me at all, as the host is in a separate area of the flat.
