I stayed at Vasco's apartment with a friend of mine. The apartment is very nice and comfortable, and has more than you need (hair dryer, shampoo, (dish) washing machine,...) and it is very easy to reach by subway (2 minute walk). It is also possible to walk from the apartment to the center of Lisbon (15min) or any of the neighbourhoods (Baixa, Bairro Alto, Alfama,...). Vasco himself is very friendly, he offered to store our luggage as we arrived quite early in the day while there were still other people checked in. He also gave us some tips about the neighborhood and Lisbon. Would definitely recommend!
