We had a nice stay at Jose/Jason's place.
The location is really great and a definite selling point! The freedom trail and tons of restaurants and pubs are literally one step away.
It was also really easy getting in touch with the host both during the booking process and once we had arrived.
The apartment itself was okay: it had a random fridge just hanging in a corner, it could use a little TLC and you could really hear people upstairs. Nonetheless, it is a great choice if you plan on spending your day out in Boston. I'd still recommend this place.
