I'm a grad student who stayed at Zach & Betsy's house during a research visit to UMN. I'd definitely recommend the place to others in the same situation, as hotel prices around UMN have gotten exorbitant with Vikings/football events, and it was not that far from the university...easy ride on the #2 bus and only 2-3 blocks to Franklin St. Bakery and Maria's Cafe. Amazingly comfortable bed, fast WiFi, and I couldn't believe how quiet the neighborhood was at night, despite it being rather densely populated and close to the interstate. Lots of pleasant conversation at the home when our busy schedules happened to coincide.
