Oscar's place was a wonderful place to stay for my week in Lisbon. It's close to the metro and buses run by the apartment as well. But it's nice and central and I walked everywhere.
The apartment is spotless and Oscar is a great host. He was always offering coffee and advice and he was a great help in figuring out the city.
The room was great and, though the apartment is very central, the room was totally quiet and peaceful. He has the place equipped with great wifi, the shower is great, the kitchen is fully equipped, and there's even a TV in the room, though I didn't use it.
Oscar's place is great and I would stay here again and recommend it to anyone thinking of spending some time in Lisbon.
