Sofia's place was exactly what we were looking for -- convenient to the airport for a one-night stay in Lisbon before starting out on a road trip around the country, affordable, and very comfortable (the bed is super-comfortable). Being convenient to the airport does have the downside of hearing the planes coming and going, but it actually never bothered us at night. (A white noise machine helped.) Sofia is a great host -- friendly and very quick to answer any questions that arose. And the apartment's a relatively easy walk to a couple of supermarkets, the Gulbenkian museum, and a number of restaurants (in fact, Sofia mentioned that there was at least one restaurant in the apartment building, though we never got a chance to try it). It also has the major advantage of having a parking garage. Would definitely recommend.
