This place was within extremely walkable distance from some of the sights in Porto (Sao Bento station, Torre dos Clerigos, and Se do Porto for instance). We also easily walked from those places across the river to Vila Nova de Gaia to spend an afternoon.
The parking space itself was large, but the entrance is rather tight. I could imagine that getting into the garage from the narrow street could be problematic with a larger vehicle. However, it was great to not worry about finding parking after a day trip out of town.
Apartment itself is clean and had all the amenities needed - shampoo, soap, hair dryer, iron/ironing board, etc. Overall a good deal for this place!
