A nice place to stay in Shin-Okubo, Japan's Koreatown. It's very close to the station with the Yamanote Line that stops at a lot of popular areas to visit. Ohkubo-san's place is perfect for decompressing after a day of traveling in the walking city of Tokyo. The one flaw we ran into when visiting was sewer gasses somehow made it into the apartment through the bathroom on more than one occasion and was unpleasant when showering.
