Clean, modern studio apartment that was a short walk from main tourist sites in Porto. Easy to find and easy communication with the hosts.
Worth noting - we chose this Airbnb in part due to the late check-in time, knowing that we would be arriving into Porto on a evening train from Lisbon. The listing said that you could check-in until 1 AM. Future guests should know that they charge an additional 20 euros for a "late" check-in after 8 pm. (hidden in the house rules section). We were also surprised to be asked for this in cash upon arrival (something that goes against AirBnb policies).
Other than this, we had a nice stay and no issues with the apartment.
