Obviously the hotel had just changed hands. There were no signs from the main road, so it took us a while to find it. We were hoping to eat in the restaurant to save driving into Aguilas again, as there were no other restaurants nearby, but we were told it wasn't open that night.
The manager was very helpful & he did apologise, & said the signs were on order, no doubt in a few months these glitches will be ironed out.
