The hostel is very well situated in the city center. On one side you go to Praça do Commerce in less that 2 minutes, on the other side, you to have drinks in Bairro Alto in 15min walking max and on the third side, you are in Alfama in 5 minutes!
The room was cute and clean, and the common area (mostly bathroom) is used but still ok and honest compared with the price.
We stayed just one night before taking the plane back and it was just perfect to go easily in the city and back to the airport !
