I stayed in December when the area was in hibernation - and the hotel nearly too. Never encountered any staff - instructions were sent electronically, access to the hotel was via rear entrance and there keys left for guests. That said, worked alright for me.
The room was ok, a bit noisy as there is a road just below, and somewhat cold as the glass door doesn't provide much insulation, so had to leave a/c on heating quite a bit.
Location is central to Arenal, just block away from the shore and short walk from buses to Palma.
The price was competitive so all in all, this was ok for me and served my purpose.
