We have had a great 2 days stay in Nuno & Susana's place. The location was perfect for exploring Lisbon; there is a subway station and multiple bus stops right around the corner, but the apartment is in a great central location, so we walked to most places.
Also there are a lot of minimarkets/shops/supermarkets very close by, and lots of caffes and restaurants within walking distance.
The location of the apartment is on a very quiet street. We had absolutely no problem with the noise outside. The apartment is very spacious. It has all the listed amenities and extra pillows/blankets for all the beds. The kitchen was fully stocked with beautiful plates and dishes and enough pots and pans to suit any cooking need that you might have.
Overall it is a great value for the money, and it is a great location for exploring Lisbon.
