For a family of four people (two teenagers), it was nice with two apartments (3F and the one above). The teenagers had the above rooms (no bathroom there but a small balcony), it worked with the four of us sharing the bathroom in the 3F apartment - which also had an electric kettle and a (very) small refrigerator. We loved the location of the iide apartment - close to Koenji station (a two minute walk away), a safe and lively neighbourhood full of shops, restaurants and everyday life. When we stayed there, the typhoon Hagibis was passing. We cannot stress enough that we had much help from Yuya during those days. We had difficulties following the news despite apps and websites in english. He wrote us several times every day with updates on weather and traffic, and as we were leaving and the public transportation was still affected by the typhoon, he arranged for a private car to take us to Narita Airport. We will definitely stay at iides again, and recommend it warmly.
