I enjoyed staying at Tianyu's place very much! He is very communicative and easy going. Check-in was a breeze! His location is conveniently located right by the Red Line, an easy two-minute walk. Maybe three minutes if you're a slow walker. It is a safe residential neighborhood. Parking is for residents only on streets parallel to his, but open to public on streets perpendicular to his. I strongly recommend staying at his place if you're visiting Boston!
