Location:the Hostel is very very close to the city center of Florence, which is great, but quite difficult to get there by car [gps - tom tom gets confused, others don't find it at all]
Rooms: we stayed in a 6 bed room. quite small for so many people, but clean and comfortable beds.
Bathroom: very small, one bathroom for all rooms (at least 5) and there is now way to look the door.
Owner: he's ok, you don't see him, except when you gives you the keys and you have to pay.
Checking in hours are flexible, i think he lives very close to the hostel, so if you know you arrive late just give him a call to let him know.
Internet: decent speed if you manage not to mistype the password :D
[see picture attached, the picture is added just as fun fact, we had no problems]
definitely worth the 13 Euro we payed!
