The apartment is very centrally located with modern furnishings. The stairs are steep as mentioned in previous reviews. Only one key so you’ll need to coordinate if staying with a group.
If you’re driving, download the Telepark app and pre book your car to save 70% on parking at Baixa-Chiado Parking (enable express entry). It’s <5 min walk to the apartment from the main entrance of the parking garage.
There is a hair stylist in the building which was convenient- 10 Euros for a wash and blow dry.
