Rafael (vera's son) is nice and friendly, he recommended us a great place for dinner. The area made us feel a little uncomfortable initially, but we soon realized that it is a safe area and the youngsters hanging around are harmless. All in all a great stay but because the room we were supposed to stay in was double booked, we had to swap room in the middle of the day and that interrupted our schedule of travelling around lisbon.
I would also like to add that communication with the host before arrival is rather difficult as rafael and vera are both busy.
