Zach and Betsy's place is good. I did not meet them personally, as they were travelling while I was visiting, but they provided me with detailed instructions and all the necessary information about the house, so that my stay was easy and pleasant.
All the little things show that they care about their guests, and our online communication was also very smooth.
Their place is a walkable distance to downton and UM. I liked the neighborhood to the north of their place much better than the one to the south.
