Had a wonderful stay at Casa Vittoria, it is located within walking distance of the historical area and buses. Silvia was a lovely host, very professional and organized, and very responsive to all our needs.
She was waiting at the apartment for us when we arrived, her instruction to the place was very clear. She showed us around the apartment and where everything is located, had a whole packet of tourist info and suggestions, even a background of history and etiquette of life in Italy. We did do one of the tours, which Silva arranged and got us a discount. We tried the restaurant downstairs, which we highly recommend.
The apartment was roomy for three adults from NYC. The queen and the sofa bed was comfortable and clean. Despite the warm weather, the high bedroom ceiling and a fan was enough to keep us cool. The kitchen is well stocked, they even had a springform pan if you wanted to bake. We didn't cook much, only made breakfast. The bathroom however, is a bit small especially the shower. We three are an average of 5'6"/150lb people and it was awkward to pick up dropped soap, so be fore warned.
I really loved Florence and had a really good experience at Casa Vittoria, that I would definitely come back.
