Was up in the Clarendon, last Tuesday. The units are nice and you get great views. The fixtures and appliances are nice and the common areas pristine and comfortable.
There are three penthouses, as you may know; these are floor-thru units at the very top below the mechanicals / lighting. They are ~3,545 square feet of space, private elevator access, separate service elevator, 360-degree views. The lowest-level penthouse gets a private terrace - the entire space above the rest of the building. Nice.
Prices are $6.75 mil, $7.75 mil, and $8 mil, or something around there.
