If you're looking to get the most out of your Denver stay, I can't recommend Robin's place enough. Her and Michael are by far the friendliest and most hospitable hosts I have had the pleasure of staying with on Airbnb. This was actually my second time staying here and it was just as memorable as the first.
The place itself couldn't be in a better location; everything one would need is within walking distance (food, 24 hour grocery stores, coffee, liquor stores, etc.) yet it's still tucked away from the bustle of downtown, which is also easily accessible walking or via Lyft. The private space is ideal for couples or singles and is very clean and welcoming -- you'll really feel like you can make yourself at home here.
Seriously, end your search here and book this place, you won't be disappointed.
