one of the best views you can get in Porto, easy to walk anywhere you want (but don't forget that Porto streets are very steep).
However, if you're going in winter months like we did, ask for extra heating equipment cause although it's 4-5C outside, the house does not have any central heating and the rooms have small electric heaters which are generally not enough, so it was quite cold at some points. Areas such as kitchen or the hall were nearly freezing, so the trip to and back from the toilet/ shower was rather challenging.
