Masami's place was easy to find and easy to enter. A little small for the five of us (we had to figure out how to put one in the lounge) but we were only there for 10 hours. The messages and explanations inside were very helpful and the property was very tidy and clean. No nearby options to use our JR pass although it was still quick and easy to get to Shinjuku and only a 30 minute walk to Shibuya.
