We stayed for four nights at Sérgios place and what can I say? I absolutely recommend Sérgio as an host!
After our check-in he gave us a lot of recommendations where we can go to or what is nice to visit. He was always available for any questions. The Airbnb is located circa 10 minutes (walk) away from Douro river, which makes it easy to go to the beach as well as to the city centre of Porto. Also there are plenty of bus stops nearby, so you don’t have any problems if you want to take a longer ride.
Our stay was definitely 10/10!
