The check in process wouldn't work. I tried emailing their 24/7 email and never heard back. The next day I tried the text option and spent a half hour on a chat with one of their people (Sonder is an international company, not just some guy). Turns out you can't check in with your computer, it has to be your phone. The check in ,still didn't work until they had me change the browser on my phone. It seems that Safari isn't supported.
The place seems like it is a reworked Motel 6. The layout and decor were pretty good. It is right next to the highway, but I never heard any traffic. However, there was a strange ticking sound in the walls. It wasn't constant, but it was never gone for long and it was in more than one wall. I can't imagine what was causing it, but it was a little annoying.
The location is good. Easy access from I-25 and close to restaurants, breweries and parks. There is a good trail along the river very close to the place.
