My partner and I stayed at Sean's place for 4 nights and it was perfect for us. Cannot say enough about the location. We walked everywhere and found the spot really accessible. Downtown was about a 15-20 minute walk; East Sixth Neighborhood was about 15 minutes (great spots to eat, a bunch of breweries, etc.). The house is also very close to Lady Bird Lake - you can walk to downtown via the river and it takes you straight to Congress Bridge / Downtown.
The spot itself was very clean and it had all of the amenities we needed (coffee maker, small fridge, microwave). It was awesome to open the fridge and see that Sean had left us a few beers from his favorite brewery - a nice treat!
Sean was very responsive and offered a lot of tips for touring around. He also let us use his land chairs to wait in line at Franklin's BBQ.
Would stay again if we return to Austin!
