I spent three nights on my own at Valentina's place. The flat is located in central Florence and its whole atmosphere is lovely. The flat is in the 3. floor and there is no elevator in the building (for me it was not a big issue). Many supermarkets, shops, restaurants, bars are in the street andin the neighbourhood.
The check-in was through a keybox-code. Although I did not meet Valentina personally, she was very friendly and helpful. The whole flat is very clean, the kitchen is well-equipped. The room is big enough for two people and the beds are really comfortable.
I would love to come back!
