master boiler/chiller system

this hotel has a master boiler/chiller system with heating and cooling being controlled universally for all rooms. They place a useless thermostat in each room to make it seam as though guests have control even though they do not. Staff is either not trained properly in explaining this or are infact told to continue w/ the sherade causing addititional frustration when pre-set temperture is not adequate at night.

We were staying in Port Forum for an event therefore the hotel was ideal. Bit far from the city centre if that's where you want to be but only about €14 in a taxi or a 15 min tube ride so not a massive issue. The pool area is lovely with panoramic views.

We didn't enjoy our stay here at all. I was with 3 friends and we all had different rooms but none of our televisions worked. When we asked the front desk they told us they couldn't do anything for us to look for cleaning lady to help us. So after finding someone and wasting an hour of our day we are told they don't know how to fix it and walked off. Another day I ordered room service so I could work in the morning and cleaning staff left it in my room for 2 days to the point my room started to smell so I finally just left it in the hallway.
