We stayed at the apartment for 2 nights and really enjoyed our visit. The place is located centrally right in the heart of the Ribeira with two small supermarkets in walking distance. The host personally gave us detailed (insider-) information for a perfect start into exploring Porto. Especially his recommendations about restaurants proved to be excellent. Also the offered breakfast-service turned out to be a really good choice.
The apartment itself is spacious and has a nice atmosphere. All in all we had a great time at the Ribeira Apartment and would absolutely recommend that you stay at this place if you visit Porto!
