I stayed at Britta's condo for a week while in ATX on business, and to say I was satisfied with the accommodations would be an understatement! The apartment is beautiful in every way. The location is quiet, safe, and easily within walking distance of everything downtown. (I walked to work every day, even in the rain — it was that close!) Communication with Britta was easy, and she was extremely responsive.
If you're staying in ATX for any reason, book this place! You will love it.
