It is possible to keep the luggage but the place is pretty packed. So i am not really sure how much space there is as a luggage room.
The same for us; we arrived early and held our bags till check in. Oh, there is a wonderful organic bakery very close by. Out the door, to the right, next corner :-)
When I stayed, they very graciously held my bags before check in while I wandered about town. They likely would but you can call to confirm!
