Unfortunately we didn't get to meet Jamie and Aja in person, as they were on vacation, but they were keen and prompt in responding to all my messages.
The space has everything you would need: clean sheets, clean washroom, AC, and free coffee (there's a Nespresso machine that we took full advantage of). There wasn't a full kitchen (just a microwave and a mini fridge), so it was a tad awkward to do the dishes in the washroom, but we only had a couple coffee cups so it wasn't so bad.
Location was perfect, in the east part of the city. Not too far from downtown and close to a lot of local places to check out. The only thing is the noise. The house is located very close to a main street, so at times it was hard to fall asleep, but they do provide ear plugs and a noise machine that helped a lot.
All in all, we had a wonderful time in Austin, glad we were able to make this our temporary home for a few days!
