I must say that my experience here has been absolutely terrible.
Room:
Total rubbish. My room is wedged between the elevator banks, so I get to hear endless amounts of foot traffic, as well as the rock concert that was going on downstairs. WC had hairs that didn't belong to me. Door to balcony window, which doesn't open fully (to prevent me from jumping out and ending this miserable stay), looks like it is still damaged post-bombing.
I describe the room further here:

I chose to overlook all of this until today...
If you want a good business suite, you need to decline heritage wing and opt for 20 years old modern wing. The problem - no views. Given heritage wing building is old, which means really old bathrooms, which means VERY small bathrooms, you need to decline upgrade and ask for 4 rooms of lower category below business suite with Kremlin views, which are part of upgrade pool.
