The Grand is always a good bet, and decent for the price. That said, I paid for a "Privilege room" upgrade, but was surprised at the room I got, which still didn't have a separate desk space or proper table to work at, just a shelf under the TV which was not ideal, and the room was smaller than expected. For a "recently refurbished" room the furniture was rather shabby and sparse, but the bed was huge and comfortable, and the bathroom was nice and fairly quiet.
The room was at the end of a corridor which seemed to be next to areas still being stripped and rebuilt, but nonetheless quiet overnight.
I'd stsy again for sure but wouldn't bother upgrading!
