Just stayed a week in Riverside. Not a bad place, except maybe getting a taxi was not always easy and the area arround the hotel is pretty dead. Otherwise, got an upgrade to the 11th floor (11th and 12th are executive while 11th is non-smoking). Lounge was decent, a bit low on alcoholic drinks, happy hour 18-20 with soft drinks available also later (lounge closes at 23). Breakfast is poor in the lounge, I recommend going to the restaurant, however it is not stellar there either. Gym is also a bit on the low side, swimming pool avaialbe (did not try though).
