Professional adult male looking for guesthouse or house share (San Antonio)

Quiet, responsible, friendly adult professional male looking for guest house or house share/room rental.
Preferred area is in or near Alamo Heights, or nearby area.
I am a non-smoker, non-partier and I work during the day.
I do have a small, very friendly dog so if there is a fenced-in backyard, that would be a huge bonus.
Please let me know what you have.
Thanks!
