This apartment is just as described. I cannot imagine a better location for a stay in Florence. It is literally walking distance to everything!
It is very comfortable - we were a group of 9 women - with a large living room/dining room in which to gather, a nice sized kitchen with large refrigerator, and great beds. The shower in the larger bathroom is a typical size for Europe, not as large as American travelers may expect, but we had hot water consistently. The second bath is actually a shower bathroom combination - odd to some - but it actually afforded a roomier shower. Initially we had a problem with it leaking under the door but the owner responded immediately and fixed it.
It is in a very popular gathering area so the noise outside at night could be a problem if you are expecting a very quiet place, especially if you want to leave the windows open at night. However, the use of earplugs allowed for very quiet, peaceful sleep.
It is close to many restaurants. I would recommend avoiding the one closest to the apartment in the piazza and walking to others for quiet and better food. One of our favorite dinners was across the Ponte Vecchio (very close walking distance to the apartment) and on the river - Golden View.
Overall, I would highly recommend this apartment to anyone that wants a comfortable, very well located place in Florence. The owner is very easy to work with and quick to communicate.
