Because we spent two of the coldest nights in Porto this year (even though it was the end March), we felt that the room was a bit too cold, even with the radiator there. And make sure you realise you stay in the central area, in a building with very old windows; there is a lot of noise at night. Apart from that, we enjoyed the stay, especially given the location (exactly near the Clerigos tower) and the fact that we could leave our luggage downstairs before checking-in. The host is a very nice and helpful person, too.
