First of all, as other guests have mentioned, the location was amazing! Only a few stops away from Ikebukuro, and even to some big cities in Saitama, and the grocery store was literally 10 seconds away from the place lol. The host was VERY fast in responding every time I had to communicate. We had a problem when we checked in, but they responded RIGHT AWAY and solved it right away in a very polite and apologetic manner. My 5 year-old son also loved the HUGE bath tub, he could play in there for a very long time lol. The laundry was very easy as well, as they had many hangers and the drying rod to hang every clothes you washed.
There isn't a sink to wash your face or brush your teeth, but if you get used to washing your face and brushing your teeth in the kitchen, it's not a problem!
Will definitely recommend for the price!
