We stayed in Antonella's apartment for 3 nights. Communication beforehand with Antonella was great and she was very helpful with directions and public transport options to get to the flat and accommodated a change in our arrival time with no problem. She was unable to meet us for check in but her partner was there for our arrival and he gave us excellent instructions and information on everything we needed to know regarding the flat, nearby conveniences and what to do in Florence.
The flat is very clean and comfortable, very nicely decorated and is well equipped with everything you need for a short (or even longer term) visit. The linen and towels are of good quality.
The flat is at the top of the building with a few flights of stairs to ascend before getting there (there is no lift) but we did not find this to be a problem with our luggage. It was a very hot weekend in Florence but we managed to keep the apartment reasonably cool whilst we were out by closing all the windows and we turned on the air conditioning when we were there which was effective.
The flat is well located and within walking distance of all the things you are likely to do in Florence. There is a supermarket literally around the corner and quite a few local restaurants. It was very quiet in the evenings with no street noise which was wonderful.
We had a fabulous stay in Florence, loved Antonella's apartment and would definitely stay there again!
