horrible service and room at that price
I booked this one while it had a discount (note: given this hotel's high price, its discount price is still more expensive than nearby 4-star hotels). When I checked in, the front desk girl ignored me on purpose for 5 minutes: I was standing right in front of her and there was no way she didn't see me; yet she didn't even look at me or indicated in any way that she would take care of me any time soon. The guy next to her had to pat her arm to hint her what she should do.
The room I got was right next to the elevator, on the second floor, with its window facing a busy street. It was noisy the whole night. The bed was small and uncomfortable. Basically I felt that this is a crap room they couldn't sell to anybody and finally gave it a discount, although with even less price a friend of mine stayed in a 4-star hotel nearby and was treated extremely well.
Conclusion: if you are willing to pay 500 dollar per night, I guess they have some really fancy room for you. However, don't get attracted by their big discount: with the same price you'll find a much better room in a 4-star hotel.
