9.2/10 Wonderful! (1,556 reviews)
Beautiful architecture from 1910. Huge fireplace and marble stairway, a second room with very comfortable common space and fireplace. Free coffee in the morning and water purifiers and ice on odd numbered floors. Yards away from A.C.T. plays and plenty of restaurants and Union Square. Parking garage around the corner. Rooms are decent, but they could benefit with an upgrade. We'd stay there again.
