We were quite pleased with this comfortable, well-maintained apartment that provided us with all amenities we could ask for. It's situated in a building on a quiet (in the daytime) street with many interesting restaurants and bars within easy walking distance in just about any direction. At night the character of the street changes and it attracts quite a lively crowd, though most street noise is effectively reduced by modern insulated windows. For our needs, this was an excellent place to stay during our visit to Porto.
The apartment is beautiful and located on a lovely street. It is near all the major tourist attractions in the city center as well as many restaurants and shops. Communication with the host was excellent and prompt. The only problem is that the apartment backs up to a night club that plays loud music deep into the night (and we were there on a Monday and Tuesday night), The music did not disturb us in the front bedroom facing the street. However, the person sleeping in the back bedroom had trouble sleeping even with ear plugs.
