Great location a few minutes walk from Santa Maria Novella and an easy check-in thanks to Valentina.
The room has air con, a good-sized wardrobe and a comfy bed, as well as a stocked fridge with cold water for a euro which I was especially grateful for. It was also very quiet.
The only downsides were the air quality, as another reviewer mentioned, and the fluctuating temperature of the shower. But it's situated in a beautiful, very old stone building, so maybe there's nothing that can be done there.
