This is a great location, just a block from the beach and in the heart of great restaurants and things to do on the north end of the city.
It's a fourth floor walk-up apartment, so not for everyone, and the penthouse itself is two floors, with a huge master bedroom and living space downstairs, and three bedrooms and a balcony on the upper level. There is only one bathroom upstairs, so it might not be ideal for four couples, but our family was very much at home here. The huge whirlpool bath and the large balcony facing north [a shady spot] were the perfect antidotes to a hot summer weekend.
We seemed to be the very first tenants of the new space -- the furnishings were spotless, but there were a couple of basics missing, like garbage cans (!). The hosts were quick to respond to our request for help and I'm sure they will have it fully fitted out for future tenants to come. We enjoyed going first and think you will, too.
