The deli only has one sleeping area, adjacent to the showers. Enter the deli, walk past the first, long counter on the right. At the end of that counter (i.e., before the second counter, which has coffee, desserts, etc.), there's an opening in the wall on the right and a corridor. Walk to the end of that corridor. When you can't go any more, turn right, then left and you'll be in the shower area. Reception desk is on the right, and the sleeping/rest area is opposite the desk. Check in at the desk and you will be assigned a sleeping/rest room if one is available.
