Silvio's apartment was a great place to stay while visiting the city of Porto. The location was in a quieter neighborhood, which we really enjoyed, and we also had easy access to all the sights in Porto.
Adriana went out of her way to help us (we arrived later than we'd expected and she was ready to let us in and show us around, she also answered questions via phone, etc.)
The view from the apartment was lovely and all the amenities we needed were provided.
A great stay and we'd recommend it to anyone!
