This apartment was the perfect size for my husband and I. It's beautifully decorated, in an excellent location, and quite comfortable. Porto is very hilly and the street the apartment is on, while not the steepest, is definitely an incline. So if an uphill walk at the end of the day isn't your thing, this spot may not be worth it. But there are wonderful restaurants and cafes nearby, plus the metro and a grocery store are within about a five minute walk.
The construction is extremely loud during business hours, which seems to be around 8-17h on weekdays. Luckily, we were prepared for this thanks to David's warning in the listing. Plus we were out of the apartment for most of the day, so it didn't really bother us.
We did have an issue regarding our sheets, they seemed to have some spots on them after washing. David was very quick to have them changed out though.
Overall, David was super helpful and we had a great stay in Porto.
