I have stayed in Casa del Sol for approximately 2 months as a visiting researcher in 2009. It was a great opportunity for short term stay as most of the places in AnnArbor are rented by at least one year. Marta is a wonderful host sharing her quiet home with guests. She is very helpful with advice and practical tips for those newly arrived in town. Casa del Sol is conveniently located with a sense of privacy and yet close to ity centr and bus communication. I would highly recommend this to anyone visiting Ann Arbor.
