We enjoyed our stay at apartment. The place is comfortable, bright, and clean. We stayed there three night, two on weekend and Monday night. The construction of the metro station, right in front of the apartment, for some reason, last through Monday night. However, the noise is not too bad if you close the windows.
Adriana and André are easy to reach if you have any questions or issues. Important things to us such as churches, shops, and bus stops are nearby. Overall, it is an excellent place to stay in Porto.
