The house was lovely. I stayed in the Master Bedroom, which was very spacious with high ceilings and lots of windows. It was as clean as one would expect, and I arrived to a pitcher of water and instructions on the mantle on how to access WiFi, taxis, etc.
It was my first time sharing a washroom, and while it is not my personal preference to walk through a common area to get to one, there were no issues and it was available when I needed it.
I never actually met my host Barney, though he was incredibly helpful in our messages. He provided plenty of directions and was proactive in contacting me. I did briefly encounter Mary, who had a rather loud speaking voice, but who was very friendly.
I felt safe in the neighbourhood. It's about a ten minute, rather scenic, walk to the subway which took you just a few stops into Boston's downtown area.
I would recommend this listing.
