Really nice flat in the heart of florence. Everything you need. The owners are really nice and answer really fast for any questions. WiFi works super smooth, there is well equipped kitchen and two really nice bathrooms.
In can be a little loud sometimes on the streets at night, but that's basically everywhere in florence-centre the case. Didn't bother us.
The location is everything - just two steps from palazzo vecchio, 15 Minutes from the railway station.
