Not suitable for ten people. Not clean.
This is a small two bedroom, one bathroom duplex with an extra toilet (but no sink) off the kitchen. There is also a “nonconforming bed-space” in the basement, which is at the bottom of the stair and has no door to separate it from the rest of the house. There are four real beds, three of them twin, one queen, along with extra mattresses, one of which is in the furnace room in the basement. This is a house for five or six people, not ten. We were a group of ten.
The other problem is that the house was dirty. Not a little dirty, but hasn’t-been-properly-cleaned-for-a-long-time dirty. There was grime in the corners, gook on handles, spills on carpets, dirt trails on the stairs, clutter everywhere. The bathroom and kitchen counters were actually very clean, but nothing else was, and someone else’s toothbrushes and bathroom stuff in the kitchen was not pleasant. When we noticed that the floors had not been swept (there was hair and dirt in the corners, our feet got filthy walking barefoot) we called to ask if the sheets had been changed and were assured that they had been, so we went about the rest of our day without checking.
At bedtime we found other people’s hair and drool on the pillowcases, unidentified stains on the sheets, and blankets that appeared not to have been washed in a very long time; they smelled bad and looked filthy. The house smelled dirty and the basement and bedding mildewy.
The house was in ill repair. Lamps without shades, broken smoke detectors, three of five lightbulbs out in the chandelier. We tried to use the dishwasher, but it leaked all over the kitchen.
The yard could have been a really nice space, but there was junk in it and dog doo. The trampoline has missing springs so we were afraid to let the kids use it, which was hard. The gas grill had no gas and the grate had a lot of food stuck to it, not blackened build-up, but a lot of actual identifiable, unburned food.
We had written before booking this house and identified ourselves as a group of siblings with their spouses and kids looking to spend a week together in Denver. This place was entirely unsuitable for that and we left after two nights, paying for hotels instead (we got a refund from AirBnB).
If we had been ten college-aged people coming to Denver for a night or two to smoke pot in the yard and party; it might have worked out OK, but I would still expect it to be clean. We had asked to get in earlier than the 4:00 check-in time if possible, and Colleen did allow us to come around 2:00.
