Tommaso was a pleasure to deal with in planning our stay in Florence. He is responsive to our messages and his grasp of English was good. He was also flexible with our check-in time. On the day of our arrival we were held up and let him know that we would be a couple hours late. He was flexible and polite about this but unfortunately couldn't greet us and check us in in person. But he did arrange for his neighbour (Pedro) to do the check-in. This wasn't a problem at all, Pedro has obviously been well briefed and gave us the tour around the apartment and also provided some good recommendations for places to eat.
The apartment itself is in a great location, probably about 8 minutes walk from the train station, 7 minutes from the Duomo and 15 minutes from the Uffizi. It's also right opposite the Central Market, which is worth checking out. There is fresh produce to buy downstairs and the top floor has been converted into a lovely food court.
The apartment was as shown in the pictures and described on the listing. It's clean and comfortable with a beautiful full height window. Word of caution to those that don't read listing descriptions carefully (like myself on occasion): You will need to lug your suitcases up 2 flights of stairs, and the apartment is a duplex with the height of the 2nd floor rather low. I'm 6ft1 (185cm) and did struggle a bit on the 2nd floor. I'm ok with the bed area, but the pantry and bathroom are also located on the 2nd floor and are separated by low hanging beams. So whilst the base height is 175cm, you'll be further ducking under those beams. And showering whilst hunched is not much fun.
However, these were only minor inconveniences and didn't detract from the overall experience. I would highly recommend my friends to book this apartment with Tommaso.
