My husband and I stayed at Francesca's place for five weeks and had a very pleasant experience. Everything you need is within walking distance --great markets, parks, coffee shops, and many places to work remotely. The space is very spacious and well-equipped --we had everything we needed to cook, and enjoy meals at home as well as work from home (wifi was fine!). We loved that the neighborhood felt like an area that real Florentine's live and away from the touristy hustle and bustle, and yet, if you want to see the attractions, everything is less than a 20min walk away. Florence is known for mosquitoes so be aware, and also, I ended up grabbing some ear plugs since the bedroom window looks out onto a nearby boulevard (I am a particularly light sleeper).
Francesca was very easy to communicate with and very accommodating. She was kind and generous and welcomed us with traditional baked goods and wine. She provided extra sheets and towels halfway through our stay and promptly answered all of our questions. We fell in love with the cats and turtles in the back garden and found it hard to leave! We hope to be back soon.
