Andrea was a great host and we would stay with him again in a heart beat. He responded to all our questions quickly and helped us plan our trip. He even had a bottle of wine waiting for us in the apartment along with maps and info-sheets of Florence!
The bedroom, living room and bathroom are spacious and the AC wall units were able to cool the apartment way better than I expected and made sleeping comfortable despite the heat outside.
The apartment is as described and in a great location between the train station (for day trips outside of Florence) and the sights in the city center. The only down side is the noise level: bus and car engines can be heard revving, as if they were driving right by our heads. Anyone thinking of staying here, should consider the trade-off between the convenient location and the noise level (or buy ear plugs).
