Salome was there to greet us on our arrival at the apartment. She took the time to explain how everything worked and gave us lots of information about the area, restaurant recommendations etc. The apartment has absolutely everything that you will need for your stay in Porto and is very confortable.
A pair of trainers are advisable as everything is within walking distance but up and downhill. The 602 bus to and from the airport has a very convenient stop right outside the door.
The wifi connection is very good and there are lots of channels in English on the TV.
We stayed for a week and would thoroughly recommend Salome's apartment.
