Just did a one-nighter here. Upgraded to a suite on the 2nd floor (# 256). Large and spacious. New colours and new furniture, as others have mentioned. Personally I do find the interior and furniture to be a little "simple" and "cheap" - this "IKEAisness" reminds me of an AC Hotel. But don't get me wrong - everything was fresh, clean and comfortable. Espressomachine and an empty fridge is also a huge plus.
Was given a 4 PM checkout without hesitation. I do not think they are classified as a convention hotel, after all? Seems to be a difference in the words and terms Marriott use - convention vs. conference.
Club lounge had snacks from 16:00 till 19:00. Beer and wine is also on offer from 16:00 til it's closing time - 23:00. Supernice lady oversaw the lounge last night. Extremely service minded!
