The location is 12min from downtown Denver and it's clean with 3 bathrooms, and the hosts, adults, kids and Lola, were very friendly. But:
1. Privacy: none. I don't mind hearing footsteps from the floor above. I did mind the kids looking into our windows at 6am every morning and yelling and screaming, three mornings in a row, for a good 30min straight (it's a basement apartment and the windows are in toddler height outside). There was also a constant drill and other noise from construction that was going on at the time right upstairs from us, with zero prior warning at the time we booked. The backyard was constantly used by the family and friends, which is understandable, it's theirs, but I don't feel like going with my family in the middle of it, especially with kids running around without clothes, so basement it was.
2. Size: the pictures made it look like twice the size, with a second story. It was a very tight space, a tiny kitchen. Which would be okay if you could use a part of the outside for yourself, but there wasn't an area just for us.
3. Comfort: the beds were tough to sleep on, saggy and overly soft. There was one uncomfortable sofa and two uncomfortable seats and two small beanbags. For a place advertised for up to 8 people. It was impossible to watch TV for the 7 of us without two of us sitting on the floor or on the stiff dining table chairs. The parking spot was suddenly occupied by the plumber and we had to find a solution elsewhere, as the host responded a few hours later, while the plumber went to work over our heads.
To top it off, it was stuffy and hot in the basement unit and when we opened the windows, there was a dog poop area that wasn't cleaned up in days. Lola is a very cute dog, but I didn't enjoy staring at her poop each morning.
