I am posting this from Sheraton on the Park now.

It was quite a nice stay overall. The check-in agent was very pleasant and friendly. My reservation was pre-upgraded to one of those Hyde Park facing suites on Executive Floor and I did not have to ask for upgrade.

The Club Lounge was very busy - it sounded very typical on weekends both evenings and mornings. Drink refill was consistently done and food was not bad at all. Enjoyed the fitness club/swimming pool on the top floor (it was empty) as the weather today was not great...
