Eileen is a great host, very friendly and patient. In case of my questions she reacted very quickly and detailed. The room is very nice, with separate shower/bath and key, and you can feel completely independent. The neighborhood is safe, it's very green and quiet. You can reach the University Campus in about 15 min by walking. Her place can be reached in about one hour taking the 20 bus from the airport, leaving at either Lavaca St/16th St or at the university bus stop. Austin is really a lovely city and Eileen's place was a great starting point for excursions.
