Our stay at Massimo's place was amazing.
It is exactly in the centre, which means that you are able to walk anywhere, but it is also close to the C2 bus stop.
It is tastefully furnished, the kitchen is perfectly equipped to make any kind of meal (it even has an oven, the washing machine and the dishwasher).
Staying there was a wonderful experience, due to the position of the house, its very big surface and the beautiful atmosphere inside.
The only small problem is that the bathroom is very small, but everything works perfectly.
Massimo was a very nice host, communicating with him via sms or Whatsapp was very easy and he came on time for check-in and check-out.
The house was very clean.
Definitely a must try if you plan to stay in Florence, it is very difficult to find a similar place for the same price!
