The place is exactly as described, it is in an amazing location, 5 min walk from train station and walking distance to restaurants and tourist sites.
The room has everything you need, it is very clean and organized. The only thing you should be aware (specifically light sleepers) it is loud, you can hear the noise from the road and outside bedroom. However it is almost fully quiet from 1am to like 6am.
Check-in was very smooth, we got greeted by Massimo and he was so welcoming and helpful. The room is in 4th floor, there is no elevator BUT the building has a machine that will carry your luggage for you all the way to the 4th floor. Massimo helped us with machine at check-in and check-out.
Also, the post says check-in is after 2pm, but we arrived much earlier than that and the room was ready, this was awesome because we were able to get ready to start our day much earlier than expected.
Thank you for everything, we had an amazing experience in Firenze!
