It's nice, full service hotel with expected amenities (valet, room service, etc...). Starbucks downstairs, but be prepared for a line if you're not an HHonors higher level member (they have their own line).
ART shuttle is easy and frequent, and even if you miss the last shuttle of the day, it's a reasonable walk from the park in a pinch. You can also get an Uber/Lyft to take you to the drop off point.
Parking is $$$$ though, but many hotels charge the same. Another downside: it's a big hotel, so walking to your room with all your luggage might be a bit of a slog (can request bell hop assistance, though).
My preference is the Marriott across the street, but I generally treat them as equivalent. I'll probably switch to the JW Marriott once it's open next year as my 4* go-to.
