Stayed at the Al Diar Capital in Abu Dhabi for one night before moving to Le Meridien as it was so bad! Considering it's a four star hotel (though I've seen quite a few publications advertising it as a 5*), it's of a poor quality. The pool was closed when I was there, the service was surly and unhelpful and the area was a huge disappointment. The lobby is tiny, and the lifts fit a total of two skinny people with a case each, and even then it's a bit of a squash! The rooms have a kitchenette, but absolutely nothing was supplied - cups, glasses etc - there was nothing, just a sink! The bedding had burn-holes in it. This hotel has just been open for about 3 years, and the windows hadn't been cleaned for about 3 years either. There were dirty marks running down the length of the window, the paint was peeling and the curtains were ripped. After moving to Le Meridien after the first night (I wasn't staying at the Al Diar Capital for another night - they wouldn't move us to another room and quite frankly, the staff couldn't have cared less of our custom!), Le Meridien Abu Dhabi may not compare to other Le Meridien resorts (ie in Dubai), but believe me, it's the Emirates Palace compared to The Capital!
