I stayed for two weeks in November. The apartment was wonderful, exactly as shown in the pictures and spotlessly clean. The apartment and the building in general appeared to have been recently renovated, everything being freshly painted and in good condition.
The kitchen was equipped with everything I needed and the bathroom with rain shower head had unlimited hot water and all new fixtures. The bed was very comfortable and extra blankets were provided.
I didn’t test the wifi speed but it was fast and rock-solid dependable.
With its location just around the corner from the Ponte Vecchio I was prepared for street noise but never heard much at all. There is a large supermarket just around the corner that has most anything you could need and the restaurants on this side of the river are quite good and not quite as touristy. You might look at the restaurants aroung the Santo Spirito square for some good choices.
The hosts were great, very welcoming and accommodating. Check in and out was simple and quick. I highly recommend the apartment.
