First time using Executive Lounges at Heathrow T3 and I have mixed opinions about it. The food and drinks were great and the staff were generally very good and attentive. However, the toilets were an absolute disaster. They were seriously worse then public toilets. I'm not expecting surgically clean toilets, but these were smelly and there was urine everywhere. We were in the lounge for over three hours as our flight was delayed and not once were they attended to and they got progressively worse. I would have thought that for an 'Executive Lounge' that they would have been checked hourly. Even my local council run sports centre gets checked hourly. Poor form. I didn't get a chance to complain as my delayed flight suddenly popped up. I also paid for a shower, which for me was worth the £15 as it was at the end of a long hot day and I wanted to be fresh for my flight. However, the shower cubicle could do with a deep clean as there was pink mold growing in places. Not keen on using these lounges again.
