My husband and I spent the weekend in the Cities and we stayed at Sarah's place. We arrived pretty late in the evening and Sarah was very flexible about our arrival time. There were no problems getting access to our room when we arrived, and it was exactly what we expected. It was very cute, clean and a nice place to stay. I would say that the only issue was (and it was a small one) that my husband is 6'3", and because it's in the lower level, the ceilings were a bit low. I had no problems whatsoever, but he had to duck in a couple spots. Otherwise, he had absolutely no complaints.
Prior to our arrival Sarah was very prompt in answering all of our questions and giving us clear directions on what we needed to do. We didn't actually meet, but based on our communication, she seemed very laid back.
Her house is also located in a great neighborhood in South Minneapolis. If you enjoy running, biking, etc. it's in close proximity to the Minnehaha Creek Parkway and miles of trails.
Overall, I would highly recommend Sarah's place and I would definitely stay there again.
