Very central location in Baixa! Immaculately clean. Dozens of restaurants within very short walk. Very close to Santa Justa elevator (which is not currently functional) and Rossio Square.
There were a number of stairs up to the 5th floor apartment, which we didn't mind, though good to be aware of (I counted 100 steps total). The elevator was useful for luggage on check-in and checkout, though is very slow. Useful if you have mobility issues, though around 10-15 steps to get to the elevator.
Overall, very spacious, fully stocked kitchen (even has a small oven where we are able to cook a whole chicken), very clean. Highly recommend!
