I had a very positive experience during staying at Cristina's place. The host is very welcoming and the communication was easy. The apartment is located in the historical part of the Florence, so all the main locations of the city are within the walking range. There is the individual shower in the room and the toilet is shared. The apartment has all the necessary equipment and devices. There might be quite noisy in the mornings due to the close location to the market. This problem is easily evaded by closing the window shutters. Still, the potential guests should be aware of that in advance.
In general: recommend.
