There couldn't better a place than Yoko's. Her and Nakayama san are simply amazing hostes than can provides you with everything necessary for a nice stay in Tokyo. They help with many information on where to go and how to do including itinerary and prices. Their house is very well organised and the neighbourhood is amazingly quite for such an strategic location near subway and train just 10 min from Shinjuku. I had mean with then and Nakayama san went to shopping with me in the nearby. Fully recommended!
