The room is very central in Lisbon, close to the main attraction and to the tube station. We self checked in and didn't meet Oscar in person but he was very nice and called me before my arrival to make sure we didn't need anything.
The room is very small and maybe lacks some furniture. The door opens straight on the building stairs and lift. There are 2 bathroom in common with the others rooms, both very small and poorly furnished, but functional.
Given the price and the position I would recommend Oscar's place.
