We stayed at Emi's home with our one year old baby as a typical hotel room is no longer suitable. This house was perfect for us. It was spacious ( for Tokyo ), clean and had everything we needed ( Baby bed / toys / chair etc. ). Using the Keio line from Shinjuku isn't the easiest when using a baby stroller but doable. Can absolutely recommend it for any family with children.
Emi as a host was also excellent. Always friendly and proactive with information and super quick with responses.
