Staying at this apartment was a great decision for us. We like to walk and we didn't take a bus or taxi or other public transport for the week. It is 10-15 minutes from Duomo and about the same to Ponte Vecchio, just to give you some idea of distance. In our view, there is nowhere in Florence which is too far to walk from this apartment.
We caught a taxi to the apartment from Florence main train station, it took 10 minutes and cost €15 Euro including 2 pieces of luggage. Later in the week we walked to the train station and it took about half an hour.
You are seconds from the Sant Ambroglio market and two minutes from at least half a dozen great restaurants. Add to this wine bars close by it is the perfect location for someone spending more than 2-3 days in Florence. We happily spent 7 days exploring Florence and could have stayed longer.
The apartment is on the 3rd floor, has a large bedroom with plenty of hanging space, a well organized kitchen, comfortable lounge room with two sofas, a small bathroom with shower and a lovely flower laden balcony overlooking the Sant Ambroglio market and the dome of the grand synagogue. There is also a second bedroom upstairs which we didn't use. It is also completely private, no one can see into the apartment or the balcony.
Our host is very kind and helpful in all respects. The time and care Arianna took during our visit was greatly appreciated. We knew we always had someone to help during our visit if we needed some advice or had an important question. Highly recommended.
