The apartment is great for a visit in Lisbon. The location allows to reach many points in the city by walking. There are almost no cars going in that street (i.e. it’s quiet outside) and yet it is close to many restaurants and stuff.
The only thing I have to criticize is that you hear every step the upstairs neighbors are doing which sounded like crazy heavy stomping. Maybe it’s thin walls/ceilings or maybe we were just not lucky with the neighbors this time - it seemed like an Airbnb as well so maybe other renters would be more quiet. ;)
I am still 100% recommending the apartment, just maybe not to someone very noise sensitive.
