Grazia is a really warm host! She has a great English, she is really helpful and bright person! She helped us with restaurants and cafes, she helped us with a car renting, she helped me to make my dream come true - she said where we can find these incredible Toscana views! We liked staying in Florence a lot, mostly because of her.
Concerning the flat - it is just behind the Palazzo Vecchio and the Uffizi Gallery. There are an enormous number of good restaurants near the apartment. It is in the very heart of Florence. We walked it all in 3 days because of its convenient location.
The flat was extremely clean. It is cozy and comfortable. There is everything that can be needed while traveling and while living. There are a lot of maps and tips for tourists in the flat. It is really comfortable for 2-3 people to live here. All furniture is in good condition. Grazia is such thoughtful, that she left earplugs for guests - it was really nice :) But it was not needed because the apartment is hidden from crowd and noises.
