Apartment for vacation rental

Hi, we are a family of four (parents and two very young children) coming to PM for a week at the end of March. I’m trying to find accommodations that are fairly close to the beach but which also have a kitchen, and hopefully have two bedrooms without being super expensive!

What are the best places to find these? I’m checking out AirBnB and VRBO but wanted to check in to see if there are other sites I should be checking out.

Thank you!
