Ciro and his wife were super friendly and excellent to deal with. When we arrived (which was a short walk from the train station) they were very thorough in going through the apartment with us and explaining everything. There was even coffee and fresh fruit that he bought that morning at the market. Everything was clean and the duvets were nice and warm. The location is VERY central to everything in Florence - you couldn't ask for a better location. Lots of shopping, food and sights within 10 minutes in every direction (walking). There was some noise at night due to the location so if you are a light sleeper or have trouble falling asleep if there's outside noise, etc. then this apartment might be a bit loud for you. I had no trouble sleeping but my friend who shared the accommodation with me had a very hard time sleeping at night due to the people, sirens, etc. Also, the wifi works in the front entrance and a little bit in the dining area/kitchen but doesn't reach the bedrooms (the modem is in the neighbours apartment) so that's something to be aware of it you need it to work everywhere within the apartment. Ciro also let us know where the nearest markets and good places to eat were in the area which was very helpful.
I would definitely stay here again and think this location cannot be beat and the hosts were excellent to deal with and very easy to reach.
