It's the tiniest and most complete apartment I've ever stayed in. The shower, the AC, and the kitchen worked well. The bed was comfy, and I was able to work without any issues with the provided wifi.
The attention was also very good. I had to work the day I arrived and I was able to coordinate an early check-in with Luca.
Also, bonus points for having a very decent supermarket next to it. They even had Yerba Mate which for me as an Argentinian was very convenient lol.
I wouldn't recommend it for tall or "big" people, but it works fine if you are not planning to stay for a long time or you just need a place to sleep and take a shower after a long day visiting Firenze.
