Airbnb vacation rental advice

[Monte Blunk]

We own a townhouse in Park City, UT and have been self managing it for the last 3 years.  It rents out during the winter months fairly easily but has very little traffic during the spring, summer and fall.  What sites do people list their properties on?  Does anyone have any useful tricks to getting more bookings during the off season in ski towns?  We list on airbnb and vrbo.

There is a ton of hiking, biking and concerts during the summer months but we have not had a lot of interest in bookings during this time, except for long term renters who want it at a low monthly or discounted rate. Our rates are comparable to other 3bedrooms in the area so lowering the rates might work but I want to also think outside the box.

Has anyone used Evolve or other vacation management companies and are they really able to increase your bookings enough to cover their costs + some?

 Any advice on other ways to list the home or ways to increase bookings during the off season that other airbnb owners have used would be great.
