Our family of 6 stayed here in July 2022. From the stated info and reviews here, we were prepared for the 6 flights (plus 1 internal flight) of worn stairs; the small size of the apartment; and the lack of AC. We have had great experiences in tiny Airbnb's with many stairs and no AC before. What I was not prepared for was the lack of functionality of the apartment. There are two showers but one has no privacy; it is cordoned off from the kitchen/main room by a set of wispy curtains. The limited space is used up by decorative, not functional, pieces; for example, in the only spare corner of a tiny bathroom there is a small plastic table rather than a wastebasket, and some of the limited floor space in the living room is taken up by a decorative lamp. There are no hooks or bars for towels, no place to hang clothes and no place to set luggage. There are three places to sleep (including the living room sofa bed) and only two fans. The abundant street noise and unusually high temperatures are two things the host could not prevent, but those things coupled with the small beds resulted in very poor sleep.
On the positive side, the host and housekeeper were particularly accommodating for our unexpectedly late check in (due to train delay), which we greatly appreciated.
Because of it's good location and quaint balcony, this Cottage would be good, I think, for one or two physically fit (not elderly due to the slippery stairs) people in the cooler months of the year. For our family, it was not a good choice, and because of the challenges described above and the intolerable heat in the apartment, we ended up relocating partway through our stay.
