The place is wonderful and in a very classy building located centrally to Lisbon. Great restaurants nearby and easy access to all kinds of touristy sites. It's definitely in a residential section of town and so it is very quiet and free of traffic noises. We felt very safe in that neighborhood (indeed in Lisbon in general), even coming home late at night. The addition of a 24-hour doorman in the building also added a sense of security. A grocery is maybe a five minute walk, so if eating out is not your thing, dining in should be a breeze. One minor upgrade... I would propose the addition of a coffee maker :)
Enjoy this place, it's a jewel!
