Five star opinion!
Manuel's flat is really comfortable. My room was big, the kitchen is clean and you can find there even a coffee maker. From the Manuel's place to the tourist center of Florence you can easily walk (around 30 min) or you can take a tram. The place is really close to the tram stop.
And Manuel is very sociable person! Thanks to him I took a part in small street dancing party and tried the best ice-cream in Florence. Thank you!
