Gabriel is a very nice host. The check-in was really easy and quick. The apartment was very big and we enjoyed it. We had everything we needed during our 3-night stay. There is a supermarket just over the street. The bus stop is in front of the building and the metro station Marques was 2 minutes by foot.
About the noises in the night, we are hard sleepers and we hadn't problems about that.
Gabriel also provided some tips about restaurants and cafees, and things to visit. The communication was very quick.
We would like to come back in Porto in the near future.
