We had a wonderful stay at Andre and Halina's place. It's right in the heart of Bairro Alto nightlife but thankfully it's on one of the quieter streets in the neighborhood. Tons of great restaurants, bars, and sites are within a very short walking distance. And the neighborhood itself has a great vibe. Be aware that you're on the first floor and you will definitely hear the occasional late night partier strolling by. We had no issue with this (in fact, we liked how lively it was) but it's something to keep in mind if you're a light sleeper. The flat itself was cozy comfortable, clean, and perfect for our week long stay in Lisbon. We would definitely recommend Andre and Halina's place to any Lisbon travelers!
