Very pleasant vacation experience! Will definitely return!
My husband and I stayed at the Loews September 23-27 before heading elsewhere in Colorado to visit friends. The staff was very friendly and helpful, and we took full advantage of their free shuttle service. The 'shuttle' is just a large SUV, so during peak times (dinner, sporting events), you may need to wait (it's first come, first served). We waited a little to get to Mile High Stadium, but it was worth it rather than paying a lot of money for a cab.
We also had a rental car, and parking is also FREE - something even just outside of a large city is often hard to come by (we are from the NYC metro area, so we're used to paying for just about everything). 
The cost of Wi-Fi in the room wasn't a huge sticking point as we were able to use 3G service on our phones to access the internet, but if you're paying $10 per day, but not paying for parking or transport if you're using the shuttle, it evens itself out. While the hotel is close to Cherry Creek, it's about 5 miles from downtown so a cab will cost you, but again - take advantage of the shuttle! And if you are as lucky as we are to snag a great AAA rate, the daily cost for a quality hotel can't be beat.
Our room was very large, clean, incredibly comfy bed, and the in-room Keurig coffee pot was great. My only issue was the location of the safe - on top of the shelf in the closet. I'm short, so had I been there alone, it would have taken some maneuvering to get things in and out of it.
The restaurant, while outdated in its decor, was great for lunch on the day we arrived. The food was tasty and the service was friendly.
We were VERY pleased with our visit, and the Loews will definitely be our go-to hotel next time we're in Denver.
