This well run operation in a beautifully renovated old building located in a surprisingly quiet street is a very enjoyable place to stay. The neighbourhood seems to be one of the better ones in central Lisboa. It's architecture and urban life (cafes, especially at nearby Praca das Flores) create an authentic Lisboa feeling while being pleasently untouristic. When I stayed the apartment had a good mix of short and long term residents. Meeting other people is an option (especially while preparing a meal in the fully equipped kitchen) but not an obligation. Flat manager Nuno is super friendly, a helpful source of information and creates a good atmosphere. Therefore it goes without saying that communication prior to arrival and check in were very straightforward. Highly recommended!
