Our stay at Marta's apartment was excellent. You really cannot beat the location, it is central and was no more than a 10/15 minute walk to the sites we went to. The apartment is very quite, and we had no issues sleeping at night! Marta's mother met us at the apartment and was extremely helpful getting us set up and recommending several restaurants in the area. The apartment is clean and has all the basic you would need from a kitchen (we had breakfast and lighter meals there- there is a market 5 min down the road). I would highly recommend this to anyone looking to stay in central Florence!
