The extended stay is good, I've been there once, no issues. It's especially nice because it's so close.
I did not like the (I think) motel 6. There was a courtyard in the middle where people were hanging out all night and being loud. It was just kind of crowded and I didn't feel particularly safe. On top of that, my roommate might have been approached by a prostitute in the lobby while getting a coffee at 7 in the morning.
I prefer the "oh god no" Knights Inn which @bkerins mentioned. It has a mini fridge for beer, is maybe 60/night, and takes less than 5 minutes to get to PAPA from the parking lot maybe hitting 2 traffic lights total. They also have free continental breakfast and the staff is friendly. I've stayed there since PAPA16 and it hasn't really gotten any better or worse. I wouldn't necessarily recommend it though if you prefer something nice...you get what you pay for.
I'd say in your case go with the extended stay
