Yves and Ana are wonderful hosts and location is really good if you want to explore Porto. The apartment is close to the metro (direct line to airport), it is away from noisy streets yet it is still quite close to the main sights and old town, so you don't need to use public transportation in order to get to the central Porto from apartment. We also got some suggestions of what to see and where to eat. I highly recommend this place if you are looking for a nice place to stay close to the old town.
