Though it looks like it's on the outskirt of the Porto city center, it's really a convenient location to walk around in the city. Eugenia and her husband greeted me in person with very flexible check in schedule, and they gave me very detailed information about the apartment, the city, dining venues, etc. Eugenia also prepared some bread, butter, jams and tea for breakfast which indeed was very thoughtful. For light sleepers, the busy traffic outside might be a little disturbing in the morning when buses pass by or other traffics get into the city through the bridge connecting the other side. I found that acceptable and could enjoy my sleep there. Overall, I really enjoyed my stay at the apartment!
