Matteo met us at his place, and showed us around. The apartment was exactly like in the photos. Everything was clean, towels big and fresh.
We had a well equipped kitchen which we shared with other guests. We were very happy to see that there were snacks and drinks in the fridge. There were 2 bathrooms, both clean, but one of them was pretty small. The room we lived in for 5 days was nice, the carpet was missing though and the floor wasn't that warm.
Actually, we had some problems with the heating. It always went off at night and it was very cold. We contacted Matteo like 2 or 3 times and he said there's nothing he could do and this is how it is in Italy, however the rest of the house was much warmer. Even the hallway and the kitchen were noticeably warmer and we even left the door open when we were the only ones at the place. Our room was so cold in fact that we could not stay in there unless covered by blankets.
Although the bed looks like its a king size bed, it's actually two single person beds combined together and there is a little gap between them.
The location was pretty good, because it took us 15 minutes to get to the city center by foot. The bus station is also close, in case you want to go somewhere further.
Would recommend this place to anyone who wants to enjoy Florence in the warm period of the year, or bring warmer pajamas.
