This was my second stay this year with the last approx 5 months ago.
On that occasion, the air conditioning was not working in the more expensive privilege rooms and the staff informed me they knew, and this had been the case for months.
With the recent warm weather, I checked the website to make sure the privilege rooms are being listed as including having air conditioning as they are more expensive and in fact, they do confirm this as a feature.
Low and behold, five months on there is still no air-conditioning, but they are happy to take your extra money and promote it.
