Just stayed for a few days at Marta's apartment. Marta was in Toronto at the time so I was met by her mother Beti. Beti was so nice and welcoming. Marta was easily reachable through the AirBNB app and quick to reply if I had any questions. The place is a cute little apartment on the third floor of an old building about a 5 or 6 min walk from Ponte Vecchio...even though it's so close to a tourist area it was really quiet and the tourists don't walk down the street that far so it felt very private and residential.
The unit was clean and had good WiFi and air conditioning which was needed in late June! If you're booking just remember it's on the 3rd floor of the building (which means 6 flights of stairs to lug your suitcase up! I knew this going into it but if you are older or have a heart issue - probably not the best choice!). Also the upstairs bed is in a sort of a loft over the kitchen. It's nice but the ceiling is kind of low - I'm average height 5'10" and hit my head on one of the beams once - I had to be really careful not to do it again - so if you're 6ft tall it might not be the best choice for you! Overall the unit was a great little home away from home! Great stay! Would stay there again. ;)
