We really enjoyed the stay at Joel's apartment. It was nice, clean and cozy. The check-in was completely uncomplicated and Joel was always reachable in order to get the details needed. We only stayed one night, for which the location was perfect, as it is very central and allows you to explore Porto by foot. As the street is very lively, it can be very loud during the day and night.
All in all, we really enjoyed the stay, expecially that we had the whole apartment for our own.
