This was an excellent place to stay while attending a conference at the Colorado Convention Center. The apartment is a short 1.5-block walk from the main entrance of the convention center. There are lots of excellent restaurants nearby. A Target store with plenty of grocery items is also just 1.5 blocks away. Union Station, Denver's main train and bus station, is also easily accessible, via a short ride on the 16th St. free shuttle bus.
The apartment itself is clean, spacious, and well stocked with everything we needed, even a desk with a large computer monitor, keyboard, and mouse - very handy! The host is very communicative and easy to reach. The check-in instructions make the process seem intimidating, but it actually wasn't bad at all.
Our only complaint was noise coming in from outside. A train runs by on a regular basis (easy to get used to) and there is a bar across the street with occasionally loud patrons, especially on weekend nights (harder to get used to). But earplugs can take care of that problem. A couple of pairs of earplugs were thoughtfully supplied in the tea tray. The CVS across the street also sells them.
