I am a graduate student living in Boston.
Sunghoo was a pleasure to host. He is very self-sufficient, so much so in fact that he didn't require any assistance from me at all. He treated our home with care and in the same condition which he entered it. His communication was great- he made sure that I knew the time he was coming and even the time he was checking out. I would definitely host him again.
It was a pleasure to host Sungho. He left the apartment clean and was a great guest.
