Stayed there during a 5hr layover last week and only paid a day use rates on 79.50e arranged via email to the official email ID quoted on the hotel website. Long story but basically booked this stay to earn 2000 bmi miles and re-qualify for gold under visa signature stay 3 get to keep gold offer.
Got an exec level standard room thanks to the gold status. Enjoyed the empty exec lounge with all its offerings. No breakfast in the exec lounge in the summer, instead exec level guests can visit the restaurant downstairs and eat free breakfast there.
