I'm rating as 5 stars, because the staff here is very professional and very attentive. During the hotel's recent, annual smoke-alarm testing, the manager set me up in the neighboring Fairfield so that I'd have guaranteed quiet during a conference call. That was a creative solution which provided me with the necessary few quiet hours.
I've stayed at several of Marriott's Renaissance and Autograph Collection hotels -- Marriott's upper tier -- but staff at this TPS bests them all.
The hotel itself is showing some ageing issues, which I understand will be addressed in the new year. The beds are comfortable despite being a version behind the newer Marriott standard. The furniture in some rooms could be more comfortable; I recommend asking for a room with the newer style of couch rather than one with the sleeper-sofa style.
