We had a great stay at this lovely flat, which was located close to the river, down the hill from Parque das Virtudes. Porto is a hilly city but there were escalators to get up to the road where the flat is. The flat was clean and cosy, and the kitchen well equipped. I was given the option to check in and pick up the key at the office in the city centre, or to arrange a time to check in at the flat where someone met me with a key.
