Myself and three friends were traveling by car that's was 2.2 meters high so it took us a while to find parking but Massimiliano helped put tremendously with advice on where to go.
The address provided was not correct on google maps so make sure you confirm with him exactly where to go.
The location of the apartment is absolutely perfect. It's centrally located with a 3 minute walk to the tower side of the Cathedral of Santa Maria Del Fiore (The Duomo). For all the other landmarks, piazzas, museums, food markets, you will not have to walk more than 15-20 minutes.
The apartment was so wonderful. A two-level flat with plenty of space for relaxing and all but one couch can be used as a pull out bed. The bathroom was modern and clean. The kitchen has all you need to cook your meals.
If your hesitating on going with this apartment, stop. Go for it, you'll love it.
