Good stay!
I compared 5 hotels in this area of NYC and King & Grove won due to the bigger room and relatively lower cost. My stay in a superior queen room was fantastic. I slept SO well due to 1) super comfortable bed and pillows, 2) quiet room, 3) perfectly fitted black out curtains. I can't give it 5 stars because 1) the shower door didn't seal so a lot of water leaked onto the floor, 2) the second day of my stay I didn't have washcloths, 3) the space in front of the sink is cramped.
I'd definitely stay there again.
