What a great place! Incredible view of the ocean, just a short distance from city center, and minutes from the ocean side of the city where there are delicious fish and seafood restaurants.
These guys take a great deal of time to make you feel welcome. From the detailed welcome packet and recommendations they they provide you upon arrival, to the What's App group they maintain to ensure you are enjoying your stay, and the welcome gifts presented (wine, chocolate), you would be hard pressed to find a better accommodation in Porto.
The apartment is modern, clean, well maintained and decorated, complete with all of the household amenities you would ever need. A balcony for enjoying and ocean view while having breakfast or dinner, two minutes from the shore line and ten minutes by tram (take the tram...it is a treat!) to city center.
A supermarket open until 9:30 is an eight minute walk away. Parking is both free and easily found; and the apartment has a private garage if you are uncomfortable with you car on the street (I left mine on the street for four days without concern or issue).
I highly recommend this place, and would stay here again in a second if I was in Porto again.
