Manuel is very friendly and welcoming host. On a first day, he showed us a little bit of Florence and some good places to eat, and after that he was always reachable via sms, answering very quickly to all our questions.
The room is bigger and sunnier than in the pictures and very comfortable for three people. Although, other people live in the house (4 more rooms) place is very clean, quiet and atmosphere is friendly.
The house is located 10 min from the city centre if you go with a tram but if you walk (it takes 30min of casual walk) you pass by nice cafes and trattoria on the way to the city centre.
I definitely recommend Manuel's place!
