I enjoyed my stay in the apartment a lot. It's so spacious, very clean, nicely decorated and has all the necessary amenities/equipment for a comfortable stay. Since I stayed for a month, I appreciated the amount of storage available in the bedroom (more than I'm used to from Airbnb places).
As for the location, it's ideal: a supermarket at 1 min walking distance, a metro station at 5 min walking distance and plenty of places to eat within 5-10 min. And you can walk to the main street/ city centre in about 15-20 min. Or take the metro, only a few stops away.
Before I arrived, I received an email from Manuel, with very clear instructions about how to get to the apartment and suggestions for places to visit in Porto. I found this very helpful.
Highly recommend!
