Very nice to stay as a promotional fee.
One night, electricity was down at only our room, for some reason. We didn't know why it happened. And we didn't know how to power back. It's hard to contact with owner at the moment since middle of the night. Only that happening,we didn't like it. Everything clean yet,all facilities are pretty old.So as long as you don't mind / know how to use it, then you'll never feel uncomfortable.
(Since because we stayed too good apartment in Porto,as a same price range, maybe our standard became a bit high...)
The area is center of Lisbon. Yet a bit far from the station on foot.
When you heading for this apartment with laggage, better to take a taxi, it's not so expensive from airport / station.
By the way, several doors down, at the corner, there is a burger shop.
They were so kind!! You better try there!
