Very nice apartment, a bit smaller than it seems on the pictures but made it work for 4 weeks with my girlfriend.
Only issue was wifi, which was cutting off sometimes, but André was very helpful and offered us other wifi access, so no major issues working from the space or doing video calls etc.
A mojor bonus is the location. You have a bakery next door, multiple supermarkets, metro station and access to the most amazing view of Porto about 100m walking from the apartment. Every time we walked into the city we loved the views at the Ponte Luis bridge.
Very nice 4 week stay in Porto!
