Clean, warm, secure, well-managed, great responsiveness from host. Perfect for my needs. This is studio apartment managed by a management company, no interaction with homeowner or other tenants. Good location for back-bay. I walked to Hynes convention center and the Copley Place mall, quick 5-10 min walk.
Two small downsides: It was a walk up, which was slightly tricky with suitcase, but clearly advertised as such so I was not surprised. Also, my room was right by stairwell which had some noise from hallway during the day, but everyone was quiet and respectful at night I had zero issues with night noise over a 4-night period
