Hello. We just got back from a 20 day trip to Italy that was awesome. We stayed in apartments and booked through Airb&b and one through Trip Advisor. Recommendations for Florence was an apartment on Trip Advisor labeled " Florence Central 2 bedroom apartment with garage. It was a lovely and quite large 2 bedroom 2 bathroom apartment with a good size kitchen and living room. Looks exactly like the pictures on Trip Advisor. We had a great experience there and with the host Monica . It is just a couple miles from the main train station , a short and inexpensive taxi ride or you can schedule a NCC private driver who can greet you at train station and help with luggage for not too much money. The host can probably also arrange that for you if needed.
We walked everyday down to the Baptistry, the Duomo , Uffizi, Accademia and Ponte Vecchio. Looked like a ways on the map but it really wasn't a far walk at all. Also close by were a couple little markets to buy a few groceries for breakfast and snacks. I hope to stay there again when we return to Florence . The building it is in was very nice. Bathrooms were great too , has a washing machine also.
Our Venice apartment was great too but only 1 bedroom and 1 bath. Although the bathroom was a pretty good size and the living room leather sectional folded out to another bed. Newly renovated too. If interested i can send info in it too.
Check the Florence one out for sure , we were very pleased with the accommodations and it had air conditioning.
