Ming is a great host. She responds very quickly, she gives lots of tips and is very reasonable. She works with you and tries to make your stay the best she can. The house is located about 1-2 stops from downtown shinjuku or a 15 min walk. I searched for months and I could not find a place better than Ming's. The place is very spacious for 6 people and I would say it is reasonable to house up to 10 people, after that it may be tight. We each had our own room w/privacy. The place has a reasonable size living room we could all hang out and the amenities around the house made it very convenient. If you're looking for a house in Tokyo, look no more this house is the best you'll get for a larger group.
