Yes, they are on a platform and are futon style.

The rooms that have kitchens, do have pot, pans and utensils. You can also ask the front desk if you need something that is not available in the room. They are very accommodating.

Yes there is, very near! Hotel can give you a map, there is coin layndry in next block.

Sorry we didn't stay long enough to need to do laundry so we have no personal experience of it. The hotel does not have its own laundry room. I've seen other comments that there are coin laundry services very near and walkable, but I can't say personally which these are and where. Hope you enjoy your stay!
