Perfect location. Good accommodation for a few nights. Actually the walls are very thin and you can hear other residents, often even their conversations. Very comfortable kitchen but there was no kettle and none of the residents could find it. We received no response to a message to the host asking where the kettle was. The bathrooms are due for a deep refresh, smelling of mold and mustiness. There are some strict rules on the walls but on the other hand the quality of the accommodation does not match them. If you do a lot of sightseeing on a daily basis and stay in the apartment only overnight, the disadvantages will not bother you as much.
The stay was ok, perhaps I will return when I need some accommodation in Lisbon on short notice. 4/5.
