Place is beautiful and modern, awesome kitchen, huge bed, cozy interior.
Tina is a beautiful host, responds fast, gives useful tips about places and locations, and is a pleasant and charming person to be around.
However if you are going to visit during cold weather in Florence(when I visited it was +7 C outside) it might be a little chilly inside, so grab some warm socks and extra hoodie or sweater to wear when you are inside.
Overall really good experience and I felt like home. 100% recommend!
