My partner and I really enjoyed our stay here. It was centrally located, had good air-conditioning, and was well-stocked with towels, kitchen items, and laundry items. We had everything we needed! Martina was very good at communicating how to find the place, how to check in, and even sent a list of recommended places to visit. This personal touch was lovely!
There are a few quirks that are part of being in an older, historic building. Be prepared to carry your luggage up a few flights of stairs as this place is on the top floor! We found the shower a bit small (and I'm a petite person) and the hot water sometimes turned off on the middle of showering because that's what instantaneous gas heaters do. Again, we understand this is what a small flat in an older building is like!
Overall, we recommend staying here. It's a good place to base yourself in Florence.
