Jessica and Thomas were excellent hosts: a maintenance issue came up during my stay, and they were able to come by the apartment within an hour of me messaging them to put a quick fix in place, and had a general contractor the next business day with a longer-term solution. Throughout the ordeal, they were helpful and did a great job of coordinating everything to make sure I wasn't inconvenienced.
Beyond that, the apartment was a great place to stay: it's in a nice location, with some good restaurants, coffee shops, and bars/breweries all within walking distance, and the light-rail station is a short bike-ride away (which is as good as it gets for public transit in Denver, sadly). The apartment was sparkling clean when I arrived and decently furnished. The one nitpick I'd mention for anyone considering a longer stay is that the kitchen is a bit too small to do any real food prep or cooking beyond throwing together a salad or scrambling some eggs.
