I stayed in the lower room with the en-suite, and it was very convenient and private. The room is cosy, but there is definitely sufficient room for luggage, and there is also ample closet space and a work desk, so not a problem at all.
John was very responsive via text, so all my questions were promptly answered.
The house is in a nice and quiet neighbourhood, while also being very close to the convention centre and Seaport, which was what I needed. I didn’t need to use the kitchen much, but it seems to have everything you could need.
Overall, no complaints, everything was as expected and made for a smooth short stay in Boston. Thanks John.
