As others have mentioned, the apartment windows open onto a covered alley, therefore the air in the apartment is quite stale.
The apartment looks like the photos but the rooms are small.
The showers worked well and the decor was nice. The hosts were responsive (replaced non-functioning kettle) and location convenient to get around. Air conditioning worked well.
However, the floors were very dirty (we had to keep our shoes on), the kitchen wasn’t the cleanest we’ve encountered in an Airbnb, and one of the beds was broken and extremely uncomfortable and noisy. Despite raising this on the first night, the bed was not repaired or replaced (we stayed for 3 nights).
The other downside to this apartment was the people upstairs, who appeared to be aiming to get their 10,000 steps in nightly from about 10pm - constantly walking around the apartment for hours. Not sure if they stopped around 1am or we were so tired we slept through it. The apartment is on the first floor and everyone coming and going from the building could be heard clearly from the bedroom.
