There cannot be a better place in all of Florence! You will love staying here I'm positive. The location is fantastic! You are minutes away from the city center AND also in an area where locals live with grocery stores, shops, a post office, and beautiful neighborhood parks all close by (no need for a car), even your own gelato shop across the street! So you can take turns being a tourist in the busy city and relaxing in peace at your lovely quiet apartment or on a park bench nearby. A wonderful tram stops out front very often, sometimes even every 2 minutes, and gets you into the heart of Florence in the blink of an eye. But the extraordinary view of the city (including the Duomo) from either of two 5th floor balconies may keep you unwilling to need to venture outside! Though the 5th floor should have offered the opportunity for good exercise, I always chose the elevator. I always felt completely safe in Florence in general, but there is a locked entryway to the building and dead bolts on the apt. for extra safety.
The Bosi Art House is sparkling clean, every amenity is like brand new or has antique charm. It feels like living in a warm and friendly museum (with modern appliances!). Even the stone floors are gorgeous. When Sylvia welcomed me upon arrival I marveled at the beautiful long heavy oiled wood kitchen table; she told me she and her siblings had been raised here (maybe in the 50s or 60s) and had eaten at this table. And the paintings on every wall are so beautiful; they offer an inspiration if you want to stay in to paint or write.
And I haven't even mentioned being a couple blocks from the Arno, that famous river! You can walk along it to get to the city center if you want, maybe stop at a cute locals coffee shop in a park along the river and have cappuccino at an outside table, then continue the walk to the city center. It's probably just less than a mile from the apt.
Your hosts here are great if you need them and also will leave you in privacy if that is what you prefer. They generously solved a problem for me quickly and kindly. I stayed a month and could not be happier...unless I could have stayed forever! For now, I plan on bringing my daughter with me next time. To all future visitors--you cannot do better than the Bosi Art House!
