We were 4 people and our stay was great. The apartment is located in a well communicated area, walking distance to downtown Porto, but not too close to the touristic areas, which allows you to feel like a local and enjoy the city. Nice cafes and restaurants close by are a plus for a casual dinner or breakfast.
The apartment was clean and both the flat and the building are charming. Spacious for 4 people visiting the city and perfect for a couple staying longer!
Would definitely return if we are back in Porto!
