Teresa and Ricardo's apartment is very modern. It's location is quiet and has breathtaking views of the river. It was about a 20 minute walk to the city center, but always pleasant. Their apartment is just next to a convenient bus and tram stop that will take you anywhere if you're not up for the hills. It's also a convenient location if you'd like to spend some time at the beach where you can find tremendous seafood restaurants. We only really found the need for the bus for a quick trip out to the beach.
Ricardo came to meet us, show us the apartment and a map. Like others said, they left snacks, Port, coffee, and a delicious homemade apple pastry. This apartment has everything you need to enjoy your stay in a truly incredible city.
Teresa was very communicative through WhatsApp during our stay. Although there was some initial confusion about booking, Teresa worked very hard to accommodate us for our full time in Porto, including moving and storing our bags.
