Very clean and spacious apartment in a quiet neighbourhood - amazing value for money. No A/C but the high ceilings, many windows, and the city breeze kept the apartment pretty comfortable throughout the day. It is pretty well located - about 15 min to Livreira Lello and 30-35 min to the river. We didn’t mind the walk as there was lots of beautiful architecture/shops/attractions to check out along the way.
My only critique was that our check in experience could have gone more smoothly as no one was there to let us in when we arrived. We think there may have been a lag in communication between central office (which has access to our air bnb messages about arrival times etc) and the staff member who let us in (who was getting screenshots of our messages sent from central office). We wandered around for a while trying to get wifi to contact the airbnb company. Luckily, it turns out I happened to have cell service/roaming in Europe so I was able to call. Once in contact, someone came promptly to help us.
Other than that, we had an amazing stay and would highly recommend staying with the Porto Concierge!! :)
