Myself and several friends are renting an Airbnb condo in downtown Indy. It is a really nice place and just a couple blocks from the conventions center.
The owner sent me a note saying he has another place available for Gencon.
"Hi, I just wanted to reach out because we still have 1 condo available for gencon. It is not a condo we list on Airbnb, but it is an EXTREMELY nice 3 bedroom condo, 2 minutes walking from the convention center and includes 1 private parking spot. If you know anyone who is still interested in booking a last-minute place for gencon let and us know and we would be happy to send them some pictures and work out a deal."
So if you have a group of 6 or so this is very affordable and really nice. If anyone is interested I can give you the contact information.
