We loved our stay in this apartment from the beginning to the end. Giacomo met us very friendly, a bottle of wine was as a welcome treat. An apartment is the same as described on the photo, pretty new, very clean and light. We're in 4 including newborn with a stroller - an apartment was still quite spacious and elevator helped us a lot. We were also provided with the small bed for baby. There is everything you need for your comfortable stay with no useless staff, so it looks very accurate.
It's situated in the part of the city center, which is a bit less touristic, more quite (no problems during the night) and with a lot of really good places to eat ( we've got a good Bisteca Fiorentina at Trattoria Pallottino - cheaper then at the popular Market and the best ever ice cream at Vivoli cafe - believe me, I've tried a lot of Italian ice cream). It's around 10min walk from Duomo and 25min from central station.
The only issue was WiFi which is very slow(especially uploading) and works 3 min out of 5.
