I was only in Lisbon for a quick overnight stay; arrived at Bairro Alto later than hoped (flight delay), and was leaving pretty early in the AM to head back to the airport. The hostess on site was very communicative, confirmed I wanted a room away from street noise. My room was on two small flights up from the reception area.
Room was small but extremely well-appointed and very cute. Room size was totally fine, as I changed and basically ran out the door to see and eat what I could before it got too dark. Door entries were all key-pad–controlled, which I quite liked, because I didn't have to worry about fussy keys.
Room was also very clean, and had everything I needed for my quick stay. One great little surprise: one of the cocktail bars I had marked as a must-visit was right around the corner from Bairro. It was a convenient last stop on my walking tour.
The convenience and value of BAS was excellent. I hope to get back to Lisbon for a much longer visit; and I would definitely stay at Bairro Alto Suites again.
