This Airbnb is in a great location near lots of great places in Porto. You can walk everywhere. We stayed 3 friends on the double bed and the sofa bed.
However, there are major construction works all over Porto and one happens to be right next to this place which means a lot of noise and in our case meant through the night. The bathroom is very small and the kitchen had a very strange smell which I brought to the attention of the owners but was never addressed.
The living area/bedroom is very spacious and the location gives it 4 stars but not sure I would stay again.
