One of the nice things about this place is it is very quiet at night. While you can hear some music during the day from the Portas do Sol area, and distant Fado in the early evening, after 10 it's whisper quiet.
It's also very well located in regards to Tram 28 and the bus stops. Tram 28 is about 3 minutes away, and the bus stop is about 7. One tip, if you order an Uber, you need to have them arrive at the top of the stairs just outside the door. They can't get down the roadway right out front as it's private, but that is likely one of the reasons why it was so quiet for us.
