Staying at Cristina's place was like staying with family! On my first day, we went for a walk up to the Piazzale Michelangelo and had our light lunch of sandwiches on the steps overlooking Florence. As my plans to hike Cinqueterre fell through due to bad weather, Cristina offered to take me to visit the nearby villages surrounding Florence! (I did not go as I made other plans.)
The room is very spacious for the single bed and the private bathroom (not ensuite) is down the corridor but very pretty and comfortable - good shower pressure, hot water comes immediately. The apartment is right above the San Lorenzo leather markets so it can be quite noisy with vehicles cleaning the streets after stalls dismantle, til about 11pm or so, but I'm used to city noise so it didn't bother me. Cristina also offers ear plugs if necessary! That said, the location is so central and convenient to walk to anywhere in Florence city centre. I would definitely recommend this listing to single travelers visiting Florence. Just be sure you can lug your suitcase up 5 floors!
