We enjoyed our stay at David's house. David's family is very friendly. His fluency in 3 languages(English, Chinese and Japanese) makes it easy for anyone to ask any questions when staying over. The neighbourhood is very quiet and getting to train station is very easy, approx 5-10mins walk. There is a food street, near Musashi-Koyama station. Be sure to visit! The area is pretty central so we are able to get to most places quickly. Renting us the mobile router at a cheap fee is a mega plus. David's friend, Eric also helped us by sharing his experience and how-to when we told him we are going to Tsukiji fish market. Thanks to him that we are able to get to the right queue for the first time. I will definitely recommend this place to friends who are going to Tokyo.
