It says Old Town, but it's really the eastern edge of it, beside the Powder Tower and the Palladium mall. Metro B and the trams stop at the door, so connections are easy, and the Astronomical Clock is about 12 minutes on foot. Rooms are small and simple, as ibis rooms are, but the beds are comfortable and there's a water dispenser in the corridor. Plenty of honeymooners book it for a late first night.
