Swallow's Nest was a great first experience using airbnb. Paulo came to pick us up from the airport which was very helpful, and the flat came with everything we needed and a few other refreshments. The flat is situated in the Alfama district and was very convenient (walking distance to lots of sights and the city centre). It's also in a great location for the weekly flea market on Saturdays, and close to the train station if you need to leave your suitcases after checking out. The flat was clean and airy, and the portable wifi was a great idea too. The only downside was the slightly noisy neighbours who were slamming doors shut and stomping up the stairs in the early hours of Saturday and Sunday morning and woke us up, but this isn't a problem if you're planning on fully experiencing the night life in Lisbon.
