If you're worried about being close to action you will have no concerns with Zach's place.
I'm pretty sure there are no complaints being close to Denver Union Square, Coors Field, Mile High Stadium and the Denver Zoo.
16th street is a stone throw away that has great food, shopping, and bars.
Did you forget something from home? No worries because Target is literally right across the street. Need some coffee? Starbucks is right across the street as well.
Lastly when I travel there are two things that I take into consideration.
1. How comfortable is the bed?
2. How good is the shower?
The bed is super comfortable and the shower, while it could be better, won't be something that would deter me from staying at his place when I come into town again.
Thank you for the great place and hospitality!
