I came with my mom to see family in the area and we stayed at John's place for 4 nights, it was a really wonderful experience. John was fantastic about responding quickly to any questions and changes in our reservation.
The space itself is great, the lighting is phenomenal and the beds and furniture are all quite comfortable. It's decorated minimally, but tastefully, and has all the necessities for having morning coffee, cooking a meal, showering, etc. Loved the living room set up with Apple TV and HBO/Netflix - really great to have for relaxing at night.
The commuter rail for the West Roxbury stop is literally 4 mins away around the corner which made it super easy getting into Boston - about a 25 min trip to Back Bay. Definitely would recommend and would stay here again!
