The place is very tidy, clean and spacious. I stayed in the 6-beds dorm, and there was enough space for everybody, including my bulky luggage. The bed was comfy and there was a small locker to keep personal stuff by the bed. In the common areas you can use the kitchen, the varanda and a comfy room with tables to eat. The bathrooms were clean and organized.
The hostess was super nice too :)
The neighbourhood is safe to walk, there are 2 metro stations nearby and lots of markets, cafes, restaurants, banks.
If I'm back in Lisbon someday, I'll certainly stay here again! :)
