Response from Sebastien:
I appreciate your honest feedback and just want to address the 'Cozyness' point. Actually the description is very clear about what to expect and it does not sell it as 'cozy' even though it is for me. I live there (it's not just a renting place) and I am glad other people share this feeling too. I guess the pictures are pretty clear so what you see is what you'll get.
Comfort is a matter of individuals' perception; some people like to travel in 4* hotels or sophisticated places but it all comes down to the price you are willing to pay for it. I stayed in NY while you were here and paid 200$ a night for a basic place. With the amount charged for this apartment you would only be able to afford a dormitory in a sub-area of Tokyo, and that would a completely different experience.
Your review is quite positive anyway and I thank you for that.
I just wanted to give my view about the 'cozy' point to peoples reading the reviews.
I was very happy to meet and host and hope you'll get a chance to visit Japan again!
Best regards, Sebastien
