This flat is ok for a couple who do not mind noise and the stairs, as mentioned in earlier review. There is no AC, and it gets very warm because of the flat's many windows (which you might want to keep close due to the noise).
We were 3 people visiting, two adults & one child. I was going to sleep on the sofa bed, which I had notified the host. Yet, there were only 2 towels and the sheet for the sofa was torn and too small. The communication was slow; it took one day before I was informed of where to find a proper sheet. But by then I had decided to stay somewhere else, since it was too noisy, warm and the sofa bed was uncomfortable.
This is the kind of Airbnb that is more like a hotel (but without AC) than a home away from home.
