My mother and I stayed at Federico's place over a weekend and had a wonderful time. The view of the Duomo is spectacular and we found the flat warm and comfortable. It has everything you need- clean towels, comfy bed, beautiful views. The kitchenette is small but we mostly ate out, and, as other people have mentioned, there are a few steps to the apartment which would be difficult for people who find stairs tricky. Federico was a really gracious and kind host, giving us lots of local tips which made our stay so much better, and was kindly flexible on our check out time on Sunday. Thanks for having us, Federico!
