I stayed in Hisao-san place while im on internship at a company near Tokyo station and Hisao-san place is an excellent place for me. Best value for the price as well. The room is clean enough, well organized, hot-cold water running just fine, and the aircon works well.
In addition to that, his place is only 10 min away from Uguisudani Station (Yamanote Line), that have direct access to major train stations like Shinjuku, Shinagawa, Shibuya, Hamamatsucho and of course Tokyo station.
Finally, The sandwich every morning was awesome !!!
I'll definitely stay here again.
