We stayed at the Cha Cha Cha for a staycation while we had new windows installed in our home. Despite being just a half mile down the road from our home, it really felt like we were on vacation. We had three kids and they LOVED the pool and hot tub; my daughter (who's 2) was fascinated by all the Mexican decor. The beds are comfortable! I'm not one for a soft bed, but it felt like sleeping on a cloud.
Cha Cha Cha is in Allandale, which is a really beautiful part of Austin with lots of old trees. It's close to lots of fun stuff but far enough that it's quiet at night. This is a great place; you won't regret staying here.
