Paola was extremely responsive from the moment we booked our reservation and answered any questions promptly. The apartment was very centrally located and had all of the modern conveniences you could want or need, and then some. The bed was EXTREMELY comfortable and the AC worked great--which was very appreciated when the temps reached above 90F. There was a great grocery store just a block away so we cooked breakfasts there every morning.
Paola keeps a great book in the apartment that details clear instructions for the space as well as offers tips for things to do and see in Florence. The pizza place downstairs was really good and we didn't find the noise outside to be a problem (though we did use earplugs at night just in case, and it was very kind of Paolo to supply them, and the high-tech music pillows--which I now I want).
It was really fun having our "own" apartment in Florence for a few days--it felt like an authentic local experience.
