You will have access to one full bedroom and your own bathroom. Additionally you can use the couch and living room. You will have access to the kitchen. I'm only 2.5 miles from zilker which is a really cheap uber/lyft ride or you can walk or bike. Right on the boardwalk and it's really lovely.
I will have a blow up mattress for the main bedroom, that is very comfortable and is a queen size so you can have up to two folks on that.
