Location - strategic, very near to Okubo/Shin-Okubo station (5 min away).. the mentioned stations allow you to transfer at Shinjuku station. You can also walk to Shinjuku station (10-15min away)
House - just nice for 2 travellers. But you will be staying with the host (he will be at the 2nd floor). Privacy is an issue for me, although I never met the host by far.
Host - only response to airbnb related questions. You will get a very rude response from the host when you ask those non-airbnb related questions. However, he do answer me some of the non-airbnb related questions.
Conclusion, I won’t come back to this host if I am back to Tokyo again.
