Even though Bairro Alto can be quite noisy at night, the apartment is so conveniently located that this becomes only a minor downside. Sitting right at the heart of it all, next to Baixa/Chiado metro-station, almost everything of note for a couple of days in Lisbon could be easily reached by foot or with the public transport right outside the door. It was also clean and the handling of booking and keys etc. was uncomplicated and reliable. Would recommend this place to everyone and definitely come back.
