Book, book, book! Super friendly staff/volunteers who are also just fantastic people, dorms as described, location truly can't be beat. Just as an FYI: Bring your walking shoes for the hills, upper body strength to get into the 3rd top bunk, and know that if you're here in a warmer month you'll have fans, not air conditioning. Didn't impact my stay at all, though! Also, don't miss tapas night - Eddie's cooking was easily the best I had in Lisbon. The atmosphere they create makes for good vibes all around between guests. You won't regret staying at Lookout Lisbon!
