There are only 2 windows in the apartment: 1 in the kitchen and one in the front bedroom. All the other rooms are windowless. This means lack of natural light, and also difficulty in airing out the apartment (which explains the constant smell of dampness and mildew).
The small living room has a dining area with a table that comfortably seats 2 and uncomfortably 3: not more since there are only 3 barstools, so our 4th person had to stand. The small rooftop terrace could have been a nicer place to sit, but there is not a single chair in the whole place: virtually impossible to lug the barstools up the corkscrew stairway. I raised these issues with the owner on the first day, but he did absolutely nothing about it during our 8-day stay.
