We had very enjoyable stay here just before Christmas.
This accommodation is very convenient for sightseeing of Florence. There's cafe and a restaurant opposite and very good food market 10 min walk from the flat. There were 3 of us staying and I also did some cooking in the kitchen.
Hosts are very friendly and respond to my questions very quickly.
If I am coming to Florence again I would definitely use this airbnb accommodation.
There were 3 of us visiting but 5 could stay comfortably sharing beds.
