We stayed at Pedros place, unfortunately only for 2 days. The appartment was great and at a great location. From there you can walk around Alfama and also go to the city center by walking only in 15'. Pedro was a great host, really helpful and kind and he provided us with many useful informations on what to do in Lisbon. Another great advantage of the appartment is that is pretty close at Santa Apolonia train station which make the access really easy.
