The Domain is a great area to stay that has all you're seeking... N.W. Austin...
The Arboretum is adjacent and also well suited...
These are the areas where many/most play while in Austin... The Domain is a great outdoor mall/shopping area... The Soccer Stadium is also close by... However, this week the All-Star soccer game is in town... which may drive up hotel prices... You can also go North on I-35 and Parmer Lane for suitable and reasonable cost hotels...
I suggest to create a Bio Page to provide more info to everyone to contact you... You can also put more in your signature line as far as links to contact you, email addresses, etc. Here's an example...
