Peter has a great location if you are going to Austin for Franklin's Barbecue, Mickletwait Barbecue, Nickel City Bar (neat neighborhood bar), or the the Texas State Cemetery. All are .6 miles or less and an easy walk.
If you are going to La Barbecue (was the best to me) then it's a 1.1 mile walk downhill, but coming back you will want to Uber (plan for it to be 90+ degrees if not 100). We used Ubers or Lift for $20 to $30 for XL size to get to Allen's Boots / Tecovas (shopping area), The Continental Club, and the UT home football game. And the coffee shop that is four houses down the street was pretty nice.
The communication with Peter was great and having a key lock outside allowed our group to split up if we wanted and leave the key for whom ever returned first. The bathroom also had some extra supplies in case you forgot to pack something.
That being said, Peter needs to do some upgrades and from the looks of the back yard (construction material) it looks like he plans too. The fridge door (right side) was broken while we were there and keeping the fridge shut was not difficult but yet for $320 a night (after all fees) not something one should have to worry about. The TV had a large discoloration spot in the middle like someone had punched or thrown something at it so it needs to be replaced. When we had down time and wanted to watch TV that was pretty annoying.
The A/C units are adequate but are never going to make the inside of the house any cooler than mid to upper 70's. which with outside being 95-100 works. If you want a cold room to sleep in it's not going to happen. The kitchen (near the sink) had a leak we cleaned up several times and not sure where that was coming from.
Taking all of that into account I think $323 a night is too much when Austin has so many other places to stay. This could be a great Airbnb, but only if Peter puts in some work.
