I was here on a business trip with 12 people and by the time our rooms were booked, apparently the only ones left were at the club level. Club level - you would think that means something better than the regular rooms - well I can't say it was anything special. The room was a nice size but just basic. I did like the sink area in the bathroom, it was large enough to hold all my hair products and such :) the sheets were dirty and the towels had a weird smell - maybe from something they wash them with.
The front desk staff was friendly and they got me so hyped up about the club level breakfast on our actual floor 6-9. I was there at 8:30 and there was nothing left besides some granola bars - whomp! They did give me a voucher for their cafe, but that was simply inconvenient when on a work trip and one is limited on time. Also there was no microwave or safe in the room. There was only one dirty microwave per floor and a safety deposit box at front desk - again very inconvenient.
Overall it was just a so so experience. Not bad, but not great either.
