Vonnie & Patricia are terrific people and very hospitable. I felt very comfortable moving around the house and they were always available to answer questions and/or provide direction.
If you will not have a car and will be relying on public transportation, do a bit of research on the buses serving Chicago Ave like the #5 and #2 as well as the train system (i.e. Blue Line on Franklin) that can get you to all the places you may want to see (i.e. Univ of Minn, Lake Calhoun, Lake Ave, Target Field/Center, etc.)
