Our stay at Roberta&Rossella's was the best Airbnb experience that we have had, particularly the communication. Roberta responded to our inquiries immediately as we were making the reservation and while we were there. The apartment is charming and was ideally located for us - five minutes to the Central Market and ten minutes to all the major attractions. We took long walks every day and were always delighted to return to the quiet and peaceful apartment. Note that it is also a short (maybe 7 minute) walk to the train station and to the new airport tram (which is the best way to get to the airport).
As noted in previous reviews, the apartment is laid out in a funny way but that is part of the charm of old Florence. Both bathrooms are on the ground level by the master bedroom (be careful on the stairs as they are not the same height and depth and it is very easy to slip on the fourth step down). We didn't cook dinners but the kitchen seemed well equipped - everything in the apartment was in great working order.
Some tips: Fuocco Matta around the corner is a very nice restaurant. Mario, right off the Central Market, is a must for lunch. There is a really fun flea market on Sundays in the square one block away.
Thank you Roberta and Rossella for making our trip such a lovely experience.
