Lovely central location, right at the heart of Lisbon. Unfortunately I can't say that about the house: the room was very cold with no heating and the host did not provide anything extra to keep us warm. We travelled in January when it's not packed with tourists but temperatures can get below 10° so it's not very nice. To add to that hot water was not very hot and would not last long enough for a nice shower.
The room and house itself is quite basic, no wardrobe and very little space for stuff, even in the toilet. Bathrooms are shared between several rooms so don't expect them to be clean. Also, our neighbours were quite rude and would talk/step loudly late at night or early in the morning. There are virtually no walls so any small sound in the house can be heard from the room and will disrupt your sleep.
