We had a lovely stay at the Garden Suite. Since we had a car, having street parking (in front of their garage) made it simple and easy for us to come an go on our various day trips from Porto. Jorge was very responsive and incredibly helpful -- his recommendations for local restaurants were spot on and we really appreciated his guidance. (Especially the first night, when we arrived a bit late after a long rainy drive.).
Location is wonderful, only about a 20 minute walk to the city center. Easy to get to by car (especially in the age of GPS directions!) We had rain every day while we were there, so did not have a chance to enjoy the lush garden. It was hard to believe that this oasis was tucked behind the garage and garden walls.
The apartment is small yet very functional, making use of every inch. Given the stairs from the garage with unprotected railing, I would not recommend for children or people with mobility issues. But if you are single or adult couple, it's perfect!
