Here are my initial thoughts:

1) Hotel is new so everything seems nice and shiney
2) Checkin was a mess. Had to try 3 credit cards before the machine would accept one. It didn;t like my Amex cards and I had to pay with Mastercard. No big deal but might be if you only have Amex
3) No upgrade (I have Diamond status) - I checked in quite late and apparently there were only 4 rooms left. Again, I'm not bothered by this but some might be. I did get the king room I booked.
4) Rooms are ok sized, and bed is comfortable. Internet works well. My room has over sized shower and a bath (I can take some pictures after sevice tomorrow)
5) No exec lounge - there is one but it is closed for an unspecificed period. When I booked I was told it was open and the person at checkin told me it was open 8 till 8. It is actually open as a space just nothing to eat/drink
6) Restaurant is only open for Breakfast. It was fine this morning with a good selection of hot and cold food. For lunch and dinner there is only room service. There is a cafe that sells cakes and tea/coffee near reception
7) Fitness centre was open - all new equipment - nobody was using it the twice I passed by - it is a reasonable size - 5 running machines, some bikes, weights etc
8) Outdoor pool - closed and surrounded by workman and scaffolding. No idea if there is an indoor pool

FYI, I can see a KFC and a Pizza Hut outside my window!! There is a big shopping centre and lots of facilities in this area and you are close by the metro.

In short - this is not a 5 star hotel. It is nice, new, clean etc but 4 star is where I'd put it - especially considering some of the high end hotels in Dubai.

If you want to know more, just ask as I am here for a few days. Happy to take pictures as well if required.
