The apartment is in a great location, close to the Duomo and all the sights. Andrea met us on arrival and was very helpful, suggesting places to visit, marking them on a map that he provided. He also organised a taxi for us on our departure day. The apartment is a traditional Italian experience with all that you need.
Except, you may like to take a travel kettle with you for that reviving cup of tea or coffee, as there wasn't one in the apartment.
It is quiet at night and we slept well, especially as a new double bed arrived on our second day!
It is firm and very comfortable.
We would recommend Andrea's apartment for a great stay in Florence.
