The appartement had a bit of a hostel-vibe, with differtent young people checking in and out each night. Can be a nice way to meet new people, can also be a little noisy (but with some earplugs you'll be fine). The mattress is a bit hard and the blankets very thin for wintertime in Lisbon. Luckily the room has an air-conditioner that can blow hot air. The cleaning lady is very very kind and does a great job at keeping the place spic and span.
