Shawn's place is as described. Very spacious room with lots of light. The check-in process was smooth and Shawn was easy to communicate with. The neighborhood has quite a bit of character and gives a different feel to Boston compared to being downtown or in other areas. Also, the T was a short 5 minute walk away which is convenient.
The only reason for not giving a 5-star rating is that one night a guest was being pretty loud and it was hard to sleep. I mentioned this to Shawn and he addressed the situation. It didn't happen again.
I would definitely stay at Shawn's place again.
