First, the positives: The proximity to all Florence has to offer is great. Really couldn't ask for more on that end of things. Check-in was good and the hosts were very responsive prior to our arrival.
Unfortunately, the negatives outweighed these for us. Couple things that the ad doesn't tell you:
1. The rest of the building is students. Our first night, we got 3 hours of sleep...maybe. There was a party above us that went until 5:30am. I contacted the hosts and asked if we could move for our second night and they said that "unfortunately we have no control on what the other occupants of the building do...hence, we cannot provide a refund." (They also mentioned that they could warn them and also call the police and suggested we do the same.) I knocked on doors the next day and found out it's all students. Had I known this was the case, I'd never have rented it in the first place. I don't blame them for playing hard - we were in their territory.
2. The bathroom is tiny. As in, there's no possible way to dry off after a shower without your towel brushing up against the toilet and/or bidet. That is, if you FIT in the shower. If you're at all overweight, forget it.
3. The cleaners came in without permission to pick up the prior occupants' laundry, then showed up early while we were packing and again let themselves in. Nothing like someone else entering your room without permission to make you feel like your belongings aren't secured.
Buyer beware.
