The place is located in a very convenient location, like 4 blocks away from the train station and literally 2 blocks away from the Duomo which you can see from the window. The apartment is big, clean and nice and it was very comfortable for three of us.
It is located at a 4th floor so if you have big luggages or are not in shape, get ready.
WiFi was not that good but we managed it.
Host was on time for the check in and helped us with the hot water that was turned off by mistake. However, he seems not to be the owner and didn't seem happy and pleased to do his job. I guess it was just his personality. We sent him a message to say goodbye when we left but never replied back but it is just a detail.
In overall, the apartment is great, with an amazing rooftop to get some wine or ice cream at night and enjoy the life of Florence.
