Overall, I had a nice stay at Karina's spot in Denver. The private patio was very nice for enjoying the afternoon sun, and the apartment was nice and cozy with good internet and tv streaming options. Also, having a parking spot in a private parking garage so close to the apartment was very nice (although the clearance is only about 7' - so taller vehicles might have an issue).
The apartment has very little insulation from outside noise though, so just something to note if you're sensitive to that - you can hear sirens zipping by on Speer throughout the day/night, the elevator noises since it's close to the apartment, and can also hear everybody that walks by in the hallway or anytime someone drops something in the apartment above you.
The area where the apartment is located was decent though and the nearby grocery store was very convenient. There were a few homeless people around at any given time but that's true of almost anywhere near downtown and I never felt unsafe or anything.
