Wonderful and quiet hostel with a great sunny garden. The place is suitable for short but definitely also for longer stays. It's not a party hostel or a hostel where you will meet loads of other travellers but more for travellers that like to be on their own. The hostel is not in a tourist district (20-30 minutes walk to the center or short metro/tram ride) which can make your stay in Lissabon a bit more interesting. Lots of shops and (cheap) restaurants in the neighboorhood. If your vegetarian... then here you are in the right spot with loads of Nepali and indian restaurants!
Communication with Maria is very fast, direct and clear. Excellent!
