Everything was in order, the flat was clean, with everything we needed and we were very well received.
The location was good, close to Metro stations and to restaurants and markets, but the first night we felt really insecure when walking in the neighbourhood after dark, so the following days we got back before the dark.
One odd thing about the flat is the toilet, which was in a separate room from the shower and sink, but it did not compromise our stay.
About the cleanliness, as I said, the flat was very clean when we arrived, but about the third day it started to become really dirty and the appliances available to clean it were working properly. It was really hot, but due to the noise during the night, we had to keep the windows closed, so in addition to the dirt, it became unconfortable to stay at the flat.
