The host was very responsive. Gave us detailed directions on how to get to the apartment from the airport, which made it super easy to navigate after we landed at the airport.
The apartment was great for our short stay in Porto.
Location was excellent: very close to touristy attractions, restaurants, shops. In general super walkable if you like walking.
As others have mentioned it is on a busy street, so expect noise during the day, but we did not have issues at night.
In general it is a very nice apartment with amazing location. The only issue we had was with the shower: I am no expert but looked like mildew/mold was starting to grow in one corner of the shower cabin. And if you have long hair (below shoulder) you would need to use the hot water carefully.
All in all a great value with excellent location.
