We enjoyed our stay in Saimir and Mary's place, the communication and the check-in were really easy. The whole apartment is clean and cozy. The shared bathroom is only used by two rooms.
Our room was tiny but we didn't expect more, for two nights it was perfect.
It is well-located, close to the train station and supermarkets. It is not in the very center of Florence - still within walking distance - so its neighborhood is not so crowded and noisy.
