Tianyu is a really nice, friendly, and easy- going host. When we have problems, he always helped us. We, 4 guests, all had great time there. His place is comfy. Love to sit on his couch and work on our conference papers. Besides, his apt has a washer, a dryer, and a nice kitchen. Those helps us a lot. When we need any recommendations about Boston attractions, Tianyu always kindly tells us what he knows. I strongly recommend you to stay here.
