To me that simply looks like a list of things that people may want to avoid or clarify in certain circumstances. It's probably the stuff that is most likely to cause an issue for guests. I think these are perfect examples of setting expectations. If I am renting a car and there is no parking available, that is very important to know. I am from Idaho - if I am taking a trip to New York City it may not be clear to me that there could even be a place that doesn't have parking/that parking is an amenity in some locales. It may not occur to me that an elevator may not be available for the third floor condo in Mexico because I am used to living in the US where such a place would automatically have an elevator available in most cases. Also, I have seen plenty of people on both sides complaining about the availablity of washer/dryer and similar amenities, so it is probably a good idea to be upfront as a host, i.e. the building laundry facility is only open during these hours, or you are welcome to use my dishwasher between the hours of 9am and 9pm. There is nothing wrong with being a host with quiet hours, and there is nothing wrong with being a guest who likes to live it up at all hours, but the two parties are likely not a compatible pair.
These clarifications would not scare me away as a guest. It would make me relieved to know the expectations. I have little kids that have been bitten by dogs in the past, so I would tend to stay away from a location with a dog on premises. But I am sure that the owner and I would both be happier with me simply not booking in the first place rather than showing up and either me canceling last minute or me burdening the owner with a request to keep the dog pinned up, for example. There are plenty of guests and hosts, so I think this is just a good way to match guests and hosts that have similar expectations or realities.
