Isabelle and Cesar are very friendly hosts - Cesar provided very insightful tips to the city. The apartment is in a great location - very walkable to the bus stops and train station. It is also close by to many restaurants, Sao Jorge Castle and some of the major viewpoints.
Be mindful that you will need to walk up 3 flights of stairs and they are very narrow. Carrying large suitcases up/down will be difficult.
Overall the apartment was clean and spacious for 2 people.
