Marcos was a great host in a bit of a bumpy stay in Porto. He spent about 45 minutes the first night speaking with my parents and outlining all of the different things we could do. He was very friendly and helpful and was available day and night when we had our car broken into while we were out at dinner. We felt very safe in the apartment, which matched the photos exactly. Aside from the car issue, we had a great stay and Porto was very scenic. Just a warning to not leave anything in your car, even if it's out of view.
