The apartment has the most awesome location being right in the middle of all the sites one would want to visit in Florence. It is huge, very spacious and can easily accommodate up to 6 people with a large kitchen and two bathrooms with toilets. It was very clean. Daniel hosted us. He was great in welcoming us during check-in and making sure that we were comfortable and offered us some great suggestions about local restaurants and visits around the region. I definitely recommend this apartment with a special emphasis on its location, its spaciousness and its cleanliness.
The only thing to consider is that there are no elevators and the apartment is on the third floor. It was not at all a problem for us.
