The location in Anjos is good, next to a lot of cool stuff.
You need to manage your expectations for the apartment because it's Andre's apartment that a he is listing, not a full-time Airbnb. Thus, the cleaning is not professional. Don't expect hotel-level finishes and amenities that some Airbnbs in Lisbon have. The pictures make it look shinier than it actually is.
I'll also note that the bedroom faces the street and is quite loud. Bring ear plugs. The bed also has a weird hump in the middle.
