The house itself is nice, quirky and pretty; location is good (a comfortable walk from the Firenze SMN train station) and good as a base to explore Florence. There's a nice cafe down the road and a few restaurant options too. Our train was delayed, so we were asked to self check-in. A slight miscommunication made us pick up the wrong key and then we had an issue getting into the house. However, Saimir was really accommodating and came to help us (Thank you for that, Saimir!).
A couple of notes for other travellers:
If you have a large suitcase, watch out for the narrow staircase. It's not too high up, but if your bags are heavy, it could be a tad uncomfortable. Our room was small (as was advertised) but works for close friends or a young couple perhaps who don't mind the limited bed space. If you're really tall, it might not work for you. :) But all in all, we had a nice stay.
