Our group of three visited Lisbon to attend a conference, and this location was within convenient walking distance of the Centro de Congressos de Lisboa. The stairs are indeed steep and narrow, but only a concern for those with heavy luggage and/or large feet. Once you get to the top, it is totally worth the climb to enjoy the lovely views overlooking Belem and the river. The construction currently next door was only noisy during the day, but we were out working/exploring most of the time, so it did not really bother us. The second-bedroom loft ceiling is lower than everywhere else, which is worth noting for taller guests. Helena was very accommodating to all our requests and prompt with replies. All the personal touches throughout were greatly appreciated, and there are numerous markets/restaurants nearby for convenient dining options. Highly recommended with easy access to a variety of transit options as well!
