Fantastic place. Very comfortable. Extremely clean. Perfect location. Great spot for a single person or couple exploring Lisbon for a few days. I would definitely stay there again. And I would definitely recommend it. I would not however take my partner back there because they are a light sleeper.
The neighbourhood is quiet but the building has virtually no soundproofing. The building appears to be entirely Airbnb units. We complained about the upstairs renters and the downstairs neighbours complained about us. It didn’t bother me, but my partner struggled a lot to sleep.
Also, its oddly common but not having a shelf in the shower is frustrating, leaving you to leave soap and products... on the floor? In this case, while the bathroom was beautiful, the shower drains slowly, which means leaving products on the ground isn’t really an option either. It’s a small thing, but frustrating during a lengthier stay.
