It is a good value for money if you are 4+ people. Place needs some updates (sofa is stained, damp smell in the place - needs more ventilation rather than just AC). Nice touches of hospitality (pdf guide, bottle of wine and water at arrival).
The area we didn't enjoy - was fairly dodgy at night and loud neighbouring baby/dog (but that might just have been a weird week). The roof terrace is lovely, but once getting around Lisbon we preferred other areas as to the location itself. Maybe if it wasn't just the two of us, we would get more value from this place.
But it is as advertised, big, spacious, close to transport links (albeit down a looooong hill and then up as well).
