We stayed one week in Sonia's apartment to visit the city and its surroundings. The location of the flat was exactly what we were expecting and only 5 minutes walk from the Douro and the ocean, the district itself it one of the nicest and warmest we have seen while visiting the city and full of little shops and bars.
The center of the city is easily reachable by tram, bus and bike.
We very much enjoyed the multiple restaurants along the coastline with the view over the ocean.
Our stay was made even easier by Sonia who arranged our transfer from and to the airport. The hosts were always available in case we had any question.
