My friend and I spent a few nights here in July - it is a really cute apartment, we loved the design - the colored panes of glass give the place a very picturesque glow and the little table on the porch-area was a quiet and pretty place to hang out in the evening and have a chat before bed.
The neighborhood is also lovely, and gives you a sense of a part of Florence people actually live in rather than the hyper-touristy center of the town. There's a gorgeous cafe called Santarosa Bistrot that you should definitely spend an evening at. But still an easy walkable distance to the tourist spots.
In the end, though, there were a couple tricky aspects of the apartment.
- The key is obviously required to get in and out of the apartment itself, but also to get both in AND out of the front gate. So if you're traveling as a duo and one wants to go out and the other wants to stay in, the one going out has to be escorted out so the gate can be unlocked for them and re-locked afterwards.
- There is no wi-fi (which ended up being more bothersome than I expected as an international traveler) and there is no nearby cafe with wifi
- The lofted bed gets very hot and even though there is air conditioning, you have to blast it so that the downstairs gets freezing before the loft gets bearable.
- The shower system was just bizarre, with no curtain to go around the shower area, and the flexible nozzle was hooked on the wall at maybe chest-height, pointing straight out. The only way to take a shower was to hold the nozzle over your head with one hand while attempting to shampoo with the other, and accept that you will have to mop up a bunch of water from the floor afterwards.
