We stayed in Rui's apartment for just over a week and had a fantastic time. Rui made us all very welcome by offering to pick us up from the airport, providing coffee, tea and a detailed suggestions list of restaurants, sights and general amenities. His apartment is very modern however in the old centre of Lisbon making it a walk to most sights or the public transport (tram, train and metro). We were very comfortable for our entire stay.
