Small apartment and small room with a good situation (10 min to the metro, 20 minutes to the town center, and the Gulbekian museum and gardens are close too). My room was directly on the street, so I had to close the curtain for some privacy. There is an amazing Indian restaurant at the corner of the street (the best I've ever been to).
The key to the main door doesn't work very well. Be aware there are cats in the apartment, too.
Overall, Sandro was a really nice and friendly host.
