I stayed here for nearly three months, and had a great experience. The apartment was clean and modern, with everything I needed. It is compact, but has several different spaces, with a separate bedroom, kitchen, living room, and toilette downstairs, and a loft space with a large bed, sofa bed, and bathroom with shower upstairs. Check in and communications with the host was smooth.
The location is great as well, a few minutes walk from Santa Croce, 10 minutes walk to the Duomo, 20 minutes walk to Santa Maria Novella Station. There are plenty of stores, restaurants, and cafes, with a large supermarket very nearby.
I completely recommend this apartment for a long or short stay in Florence!
