Staff was on-point, from receptionist to bartender. The queen suite was very clean and well-appointed, with decent sunny views, and unique mid-century styling. Although I didn't use the free hotel bicycles, they are a fun perk that I'll use next time! Also, great location, easy parking situation, and overall well- designed property.
