It was a truly wonderful stay which we enjoyed very much. Thus, we can highly recommend the accommodation.
The only negative thing we found was the landlady's constant attempts to contact us, which continued even after our successful check-in and had nothing to do with the accommodation itself. Instead, we were repeatedly contacted and asked if we wanted to invest in real estate in Porto. Unfortunately, we found this very annoying because we were always worried that something was wrong when we received messages/missed calls.
