We spent a couple nights here and had a good stay! The triple room was very nice, as well as the private bathroom which was a plus for us. The common areas of the hostel are all very nicely decorated. The location was good to explore Lisbon as you can reach any place (including airport) via metro or by bus, both close. Hospitality and check-in were also great.
The only negative thing is about the other guests who are not all careful not to disturb others with noises, but this does not depend on the hosts and is a bit of a characteristic of hostels in general. Overall a good stay, would recommend! Thanks for the hospitality!
