We don't get too many negative reviews, but when we do we take them seriously.
You've helped us make the decision to put some thick mats on the tile floor above where you slept, or maybe more accurately, tried to sleep. Mats will cut down on that noise a lot.
The A/C is kept at a constant temperature, 74 degrees, day and night. After years of trying to make everybody happy, we've found that 74 is the best compromise, where people rarely complain about being too hot or cold. We've had at least 80 people stay in that room since the last time we heard a complaint about the temperature.
Even so, we would have preferred the opportunity to turn the temperature down while you were there, or give you a fan (there is one in the ceiling, and an oscillating floor fan in that room--did you use either of those). If we had known, we also would have tried to find you a more quiet space.
Concerning your perception of low value, please consider that between Airbnb fees, CO state taxes, and Denver taxes, it adds about 30% to what we earn, which is $33 after our fees. From that we subtract everything you consumed: water, maybe breakfast, electricity, the cleaners had to clean your space before and after, etc. Then we pay income taxes on what is left. At best we earn $20 per night on a shared room reservation. You get to be the judge whether we provide any value or not.
Bottom line, if you give us another opportunity to exceed expectations we will be very happy to give you a good discount on a private room to make up for your negative experiences in the shared space.
