Located at a quiet, nice neighborhood 2 stations away from Shinjuku. You need to take the Keio New Line to get there, but this line isn't included in the 72hr/24hr tourist pass so take note. There are two convenience stores at a 2 minute walking distance. The place itself is pretty chilly so you might want to turn on the heater at all times if you're visiting during the winter season, and you might find the bathroom a little small. But the amenities are well provided and Mitsuko is very communicative. The hair dryer broke down during our stay, but she kindly brought us a new one to the home in the evening. Overall a cozy place for one or two.
