I stayed at this property recently for two nights and found it okay, but not impressive. Overall I preferred the Westin.
Check-In was fairly confusing. At some point 1,000 points as welcome gift were mentioned (no other explicit status recognition), and then I was handed the room key without any mention of late check-out, lounge etc. When I asked whether breakfast would be in the lounge (or whether choosing the restaurant was also an option), they handed me a pre-printed sheet and said that this explains all Elite benefits. This included all the information that I wanted, but it was a fairly underwhelming process. Room keys then had to be recoded for late check-out.
I was upgraded to a "suite". It didn't look exactly like in EE's pictures above, but was still (just) a larger room with a couch/table area. The room had a proper work desk, but it was difficult to use the electrical outlets due to the way how lamps etc. were plugged in.
As others have noted, everything has a pretty tired and dated "old Marriott" feel - not in a "nice and classic" way, but just feels overdue for refreshing and renovating.
The lounge is not bad. On the positive side, it has food/snack offerings all day, with a fairly wide selection of cakes and other sweet dishes throughout the afternoon. On the other hand, breakfast had a pretty limited selection. In the evening, they served a (changing) hot dish (plus what looks like bread/cheese/etc. leftovers from breakfast), which I sampled every day, but never really liked. To me, the evening food offering is only good if you want a lot of free food, but otherwise just not very appealing.
Housekeeping was underwhelming in the sense that they seemed to do only one "round" on each floor and never check back on rooms that had DND out. In the early afternoon, many rooms already had a "We tried to service your room, but couldn't due to DND" placard on the door.
Location is good right opposite the central station.
