Stay here. Perfect space for a couple (with a couch for an extra guest if needed). Host is amazing, sweet, and welcomed us to the apartment and Porto. We had an early train, and after confirming the previous guest would be out early enough, our host even let us into the apartment earlier than she was obliged to. Apartment was clean, modern, and very well appointed. Location was phenomenal - just a few blocks from the main shopping plaza, and no more than a 15 minute walk from everything worth seeing in Porto.
