[Highland Park] sublet sought

Hello Neighbors, I have some friends--a law professor, an industrial designer/business owner, and their 13-year old son--hoping to get a sublet this summer in Pittsburgh. They're flexible about neighborhoods, but need a place allowing pets, and having at least two bedrooms. They're hoping to spend around $800-900/month. Any leads would be greatly appreciated! thank you, Ehrrin Keenan
