Wonderful stay for a convention - would go back in a heartbeat!
Stayed March 7th-10th while in town for a business conference at the Colorado Convention Center. PERFECT location for conventioneers - great spot for pleasure travel, too. Overall one of the best stays I've had. I was bummed to leave!
Suites: Classic Embassy Suites setup - enter a living room from the hotel hallway, central wet bar/bathroom, and bedroom along the outer wall of the hotel. Great views if you book a mountain view! The rooms are clean, bright, and well-kept, with comfortable furnishings. The hotel is among the newest in Denver, and it looks it. Of course each room has a microwave, refrigerator, coffeepot, hairdryer, iron, and safe. 
Public Rooms: soothing yet stylish, nature-themed decor. Elements Restaurant has the same menu as room service. Airy atrium with high-backed chairs near a two-story waterfall element was my favorite spot to sip morning coffee! Pleasant breakfast area surrounded by flat screens near the fantastic breakfast buffet.
Breakfast: classic embassy suites. Varied, plentiful, tasty.
Evening manager's reception: open bar for two hours with beer, a choice of wine (merlot, white zinfandel, pinot grigio), or a small selection of liquors alongside a few different snacks each night.
Staff: every single staff member I encountered was helpful, friendly, polite, and genuinely seemed to enjoy their job.
Other Amenities: pool, small gift shop, 24 hr business center, concierge desk, very helpful valets who will get you a taxi faster than you thought possible.
Location: as above, outstanding. A block from the 16th street mall, with lots of shopping and restaurants, as well as billiards, bowling, a movie theatre, and a gentleman's cabaret, if you're into that kind of thing. :)
