We were travelling with our daughter, and the room had a bunk bed fixed transversely over the head end of the double bed. No issues with this, but there was hardly any space to keep our luggage in the room since it was really tiny. The toilet and bath area were separate, which allowed two to use the facilities simultaneously, but there were no hooks to hang your clothes or towels on, probably because the partitions were all made of thin boards.
On the plus side, the rooms were very clean and tidy, and the staff were excellent, going out of their way to help us. We arrived early in the morning, and were offered an early check in when we went there to ask if we could leave the luggage in the reception while we went on a tour. Their breakfast was also reasonably priced, compared to what you would have to pay for just a croissant and coffee in the shops around the town.
I would put this as an ideal room for a budget conscious couple, but best avoided if you are travelling with kids or friends, due to the lack of privacy for bathing or using the toilet.
