Serpa Beach House was really great. Very comfortable, clean and beautifully decorated. Very well connected to the rest of the city with a variety of buses and metro. The area has many restaurants and cafes from the minute when step out of the house. It is a 30 minutes ride on the tram to the centre of Porto or a few buses to Foz. The area feels very safe. Definitely recommend Mario's place to all Airbnb guests.
