The place was great, having 2 separate bedrooms each with their own air con was a lifesaver for our two families that stayed here. The place is close to lots of restaurants and the subway. It's also not too far from shinjuku station.
Koichi provided just about everything we needed. When my daughter got sick he even went and bought medicine for her! Also even though it was very early in the morning and I'm sure he would rather be sleeping but he helped us get to the shinjuku busway with all lugages.
Overall this was an excellent stay and I would recommend it to everyone.
