When I arrived in Strange Uncle's place, I was like 15 minutes earlier than the check-in time but I found that they haven't cleaned the room yet. I left the room with my bag and went out. After I returned, the room was tidied up but everything looked like it had a long history. There were even stains and holes on the bed sheet. For the common kitchen, all the pots and pans looked dirty.
But as a backpacker, overall it's okay. The location was not bad. If you are someone who like walking, you can walk to every spot in Florence.
