Sérgio and his family are great hosts, and his mother, Maria do Carmo, is a lovely lady. They make everything to make you feel comfortable and at home, and we did. They are always asking if everything is ok or if we need anything. On New Year's eve, they even left some rabanadas and Porto wine for the guests, along with a cute note :)
The room and the house are great and very well equipped, every week they give you new sheets and towels, and every other week there's a cleaner to clean the room. It's also close to everything, grocery stores, drugstores, laundry, restaurants, cafés, and even Jardim Botânico and Douro River. During our stay, the internet speed was low in the bedroom, but it worked just fine in the dining room.
It was an amazing stay! I would definitely recommend it to everyone.
