Not a hotel at all but half a dozen canal-side cavern-rooms that have been converted into guest rooms. Check in via the Court Hotel.
Best value is room 6 which has sitting space as well as the best Domtoren view from its (public) terrace area. Rooms 4 and 5 are smaller. Rooms 2 and 3 are classified as apartments (with kitchenette), as is 1 which is across on the Oudengracht.
