I'm a regional planner and spatial data analyst from Boston.
Ben and Kate were wonderfully sweet guests, considerate and self-sufficient. I would gladly have them back for another trip to Portland.
Ben and Kate were very communicative, and my roomate cohabitated with them and it was okay. They were in our house for a few days and they were fine guests. Left a few extra stuff for us that we were able to make use, which was cool, but others that really needed to be trashed, so they were not entirely careful in leaving common areas as they found them, but nothing that I would not host them again over, as long as they understand.
I had a great experience with Ben. Everything worked out well and I'm impress how he took care of my apartment while staying there. I would host him again anytime.
