My wife and I went to Firenze for our second weeding anniversary. Tommaso's place is exactly what you see on the pictures. He welcomed us with a bottle of wine and showed us on a map how to get to many different places. The apartment is equipped with everything and it will take you 10-15 walk to get to the central market where you can have a great lunch.
We were 5 days in Firenze and every day we walked out of the apartment and we were also walking back at night. There is a Super Market like 3 minutes away (walking distance) from the apartment as well some bars, restaurants and Osterias (which are the most recommended as you will have a more homemade feeling and treatment).
We recommend Tommaso's place 110% !!!
