Ryo's place is very comfortable and in a great location which is peaceful while still being close enough to all of the action. Shinjuku and Shibuya are both easily reachable by train and/or bus respectively and from there exploring Tokyo and the wider area was absolutely no problem at all. As a host he was super helpful and very responsive on the odd occasion that I did need to contact him for something, which wasn't very often as his apartment had pretty much everything that I needed for my stay and the instructions provided were both clear and helpful.
I really enjoyed my stay and I hope that I'll be able to stay again on a future trip to Tokyo. Thanks Ryo!
