We had a wonderful stay at Marta's apartment. It was very comfortable and very quiet at night time. We liked that we lived among the locals and could explore all the side streets too.
It was very close to Avenida Metro and is a lovely walk to Praça do Comércio, Elevador da Glória, Castelo de São Jorge and many other wonderful places!
We had no problems. Nuno was at the airport to meet us, as arranged, to take us to the apartment and explain how things work. Marta left very helpful information sheet/map re restaurants, transport, sights etc. and how to contact her. We would definitely recommend Marta's apartment and look forward to returning to Lisbon and its very friendly people in the near future.
