Both or Neither
I am a vacation home owner, having worked with two different properties in two different locations. We've worked with property management services in both cases, and interviewed many more.
It used to be that VRBO was the place for longer term rentals and AirBnB was the short term place. We initially listed on both at once, but eventually only went with AirBnB because of the added cost and the lack of bookings. The host would manage the bookings and use software to help optimize pricing based on rates of nearby units and hotels. This was in one of the top city destinations, between the convention center and ball park. To minimize problems, we chose 4 day minimum and blocked out the days when a nearby area had a famous (somewhat notorious) street festival. This filters out the weekend partiers and produces higher owner yield (and reduced wear and tear). In the initial phase, our manager kept the price low and the min stay low to build good reviews, and then expanded the min stay and raised the price to position it as a premium product (there is now a special designation). Our traffic ended up being business travelers (sometimes with their family), foreign tourists and relatives of people living nearby. There is a lot of incentive to maintain your reviews and SuperHost status, and yes, there may be those that complain in order to get a discount. And there was one incident with a guest who lied and tried to sneak with a bunch of others to crash, but this was dealt with by the manager and AirBnB (but with a lot of disruption).
On the second location overseas we went with a firm with over 120 units that has its own website, references in major tour guides and that used to simultaneously cross-post across the three major hosting platform groups. However, eventually they dropped AirBnB due to the high prevalence of problem guests. They position the properties as premium and only accept properties in a certain location, key features and a recent state of renovation. A set of recommended designers are offered to owners of properties under renovations or needing furnishings. They also provide a list of supplies required, have branded linens, welcome baskets and a in-city concierge desk. They also point out when things need replacement and keep a handyman on staff, to dispatch to guests. Client problems are at a minimum here.
