Initially we were given a windowless room with absolutely no natural light. Upon request we were moved to a room that we had booked, but only the next day. However, the staff was super friendly, very accommodating and we came away very happy and satisfied.
Hotel is in a great location, walking distance to lake, downtown area, funiculars etc. Very clean, large rooms and most importantly the warm staff at the front desk. We highly recommend Hotel des Arts and would go back there when in Neuchatel.
