Yousuke was a great host. He responds after a few minutes with our concerns :)
The place and location is great!
3-5mins walking distance from shin okubo station. It is also located in korean town which is a plus if you are a kpop fan. There are a lot nearby restaurants and konbinis too.
My concerns are that the steep stairs going to the apartment since it is in the 2nd floor with no elevator. You will have a hard time if you have alot of heavy luggage.
Also, the free pocket wifi has a 500mb daily limit. So make sure you have yours before checking in.
We also got the place at a discounted rate, if this was full priced, it will not be worth it since there is no bathtub and bidet in the bathroom. But for the price that we got, it was worth it :)
