The location is really great in downtown center, a lot of attractions in walking distance, metro steps away, dining right along the street, night entertainment...
A very free and safe environment, room is small, shared wash room, elevator all small which could be normal in Europe, check-in and check-out without physical reception.
A budget tight place more for younger people, but good enough for two of us as 1st time traveler in Lisbon.
The room I booked is bright with bacolny, but I do see one single bedroom unit is one without window.
