Location: across the street from the metro station. the building can be missed easy the first time since there are big businesses right next to each other and the building is not as easily visible the first go around. there is street parking - you pay from 9AM-7PM and free afterwards. the parking was what we were most worried about but no issues at all whatsoever. we thought it was great how the Airbnb was within 10-15 minutes from all of the major attractions and great options for food and grocery shopping as well.
Bed: nice and firm. no issue
Kitchen/Amenities: the washer and dryer worked great for us. wish that there were more options for cutlery
We just had some hiccup with not having the keys be available in the lockbox at the time of check-in. We left our suitcase outside the apartment door and the cleaning lady brought it in.
The check-in and check-out process is easy and communication with the host was easy via Whatsapp and Airbnb. I would stay here again if we were to visit Porto for sure!
