The best thing about Tianyu's place is that it is very close to the red-line subway (Savin Hill station), which makes it very convenient if you want a place to just stay at night and spend time outside during the day. His place is on the second floor of the three-story house. Tianyu is very accommodating and very nice!
Overall, the place looks nice, but the bedroom and bathroom could have been cleaner. In my case, he seemed to have a conflicting schedule with the room that I was supposed to be in, so he offered his room instead (and he slept on the couch). I appreciate his gesture but I would have liked to learn about this before my arrival. It feels a bit odd to stay in his room filled with his personal belongings. Again, considering the affordable price, this is a good place to stay if you want to spend most of the time exploring Boston and nearby areas.
