Sato-san gave clear and precise directions to the place so there wasn't a need for constant communication. The pocket wi-fi was very much appreciated as well! The home is larger than what I expected. It is very close to the Ikebukuro station which is the same line to go around Shibuya and Shinjuku. Everything was spacious from the dining, kitchen and bathroom. The perfect place for big groups! I highly recommend this Tokyo home!
