It was a pleasure to deal with Todd. There was a slight issue with the bedroom door, and a repairman arrived within one hour of check-in and resolved the issue within 10 minutes, even though Todd was away on vacation in California when I called him about it. He was also gracious and generous when I realized I had checked in a few hours earlier by accident.
The place itself is amazing: big and clean bedroom and bathroom (Todd gets them professionally cleaned), very comfortable bed, and quiet. Although there is no kitchen, there is a microwave, a coffee maker and coffee in the hallway, which is very convenient. The neighborhood itself is very quiet and feels safe, and is located about 1 minute away from a bus stop. There are also several convenience stores and pizzerias a few minutes away.
I stayed there because I needed to visit a professor and a friend in Harvard. I also visited downtown Boston while I was there. It was extremely easy getting from Todd's place to downtown Boston and Cambridge on the public transit.
