Certainly get what you pay for. Lisbon is expensive to stay and this is good place for cheaper.
Location is great, quiet and close to lots of dinner/bars.
Room is very small. Wifi doesn't really work. Two shared bathrooms with shower. Shared kitchen. Never issue with having to wait. But again get what you pay for.
Might have extra fees, I was supposed to come in after 8PM which I was then told was a 10 Euro fee.
