We loved it! Mario and Niccolò were amazing hosts, they were kind and accommodating and very responsive. They have a little guide book set up with some recommendations, although I would like to add if you are just looking for a cheap grocery store, find a Pam Local.
The room was very clean and spacious, and the acrylic floor is pretty cool. The best part is the location, you can't beat the location. It was right snab dab in the middle of everything, we just walked wherever we needed to go. Everything was stocked well, and shower had a little bit of extra space compared to most of them we seen throughout Italy. Oh! And the water heater must be a tankless because we never ran out, it was wonderful. The bed was also my favorite bed we slept on, it was amazing, so comfortable with lots of pillows. Also, if you play Pokemon Go at all you are right on top of a Poke stop.
Some of the minor things, the house is dark. We opened the blinds and shutters and it is still very dark. Even the lights were so dim, especially the bathroom. The house is also much cooler than outside, in the summer this would be amazing, but in October it was just a little chilly. The staircase is also a little interesting at night and when barefoot.
And that's it. If we went back to Firenze we would definitely stay here again!
