This is a nice little hostel, and very nicely located for exploring Lisbon and only short taxi ride from the airport.
The check in procedure is super easy and means you can arrive anytime you like.
Only small improvements to be made:
During our stay there was only one working bathroom which between 5 bedrooms made getting out in the mornings tricky.
Most of Lisbon seems to have slightly smelly drains and this places does a little too but it didn’t disturb our stay.
I would recommend for anyone looking for a hostel in the city centre
