**NOTE: THERE IS AN OUTSIDE LEASE THAT IS REQUIRED BY THE HOST, and a required ID submission. It is not clear in the listing (or wasn't when we rented, and it was a surprise when we were reached out to, outside of Airbnb, requesting an outside contract be signed), but it is allowed by Airbnb (we did contact Airbnb to make sure this was allowed and legit, as they generally say do not work outside of the site.)
I have been using Airbnb for 10+ years, and this unit/host has unique things that I've never encountered before.
First, however, the unit was clean, and the location close to downtown was GREAT! We really loved being able to walk downtown and even to the 7/11, and a little farther, to the grocery store. The house is quaint, and did our family well, when we were there for a couple days stuck inside because of the sand storms. The house is stocked well with staples in the kitchen, and the towels are plush and amazing! We enjoyed the backyard too.
As stated above, there is an outside lease to be signed, and I'd never encountered that in using Airbnb (often) for so long. While I was emailing Airbnb to ask if this was something I should be doing outside of the app, which took a couple of days, the host spammed me with a cut and paste request 3 times. After hearing back from Airbnb, I wrote in to ask why an extra lease was necessary, as there is already a contract through using Airbnb. The host was very short and then tried to convince me to cancel through the app, knowing that there was a no refund cancellation policy. "Upload on the site. Or cancel," I believe the wordage was. (Again, why I felt it should be stated more clearly that there was a secondary lease, so that the guest can be better informed before they do enter into the rental contract.) She stated that we could cancel, but she could not do it for us. But, it is known that hosts can cancel, without adverse repercussions or fees.
The communication style of the host, which is personal I understand, was forceful and a little stressful. We were coming in on a late flight, and it was stated very strongly in the "welcome" letter that if I didn't receive the codes for entry, and failed to remind the host to send the codes before 6pm, my family and I could be possibly "stranded... because the host turns off the office phone promptly at 6." Luckily we weren't coming through on a long flight without cell service, but we were landing well beyond the 6pm cut off. If the flight was late and we had to fly from across the country, we would have just had to trust that the door lock codes came through during the flight. (Surprisingly, she was available when we landed. But, then why put that in the welcome letter in the first place?) Some of the house rules and requests were along similar lines, rather threatening/passive aggressive ("we'd hate to charge you for ______"). It's not all out rude, but made us feel less welcome.
It was 90 degrees a couple of the days we were there, and only slightly less the other days. There is a strict rule of not turning the thermostat below 74 degrees. My wife runs very hot, and in the bigger bedroom the vent isn't close to the bed, but we couldn't even get much AC relief because of this rule. It's apparent that the unit is old, and they are trying to preserve the life of the unit, and putting that on the comfort of the guest. Again, this is where a house rule told us, "it will cost you a lot if the pipes freeze from overstress and break." In my experience, AC units are fine to go below 74 if they are normal units. In the summer in Vegas, it often gets over 100, and the nights don't stay cold enough to lower in-home temperatures. I find that threshold to be a little high.

The last thing that I'd not encountered before was a 65$ late check out fee. We had a later flight home and just needed an extra hour to get up and get out, but were quoted this price, for a 430pm check out. We only opted to do so when a sand storm hit and we weren't able to go play tourist downtown like we had planned.
Long story short, the unit itself was fine, and the location great! The interactions with the host were more pressured than they needed to be.
