Everything was ok except the following.
1. Portable Wifi was provided but host did not mentioned that the Wifi is only limited to a certain usage. Let's just put it this way, I can only Google my way in Tokyo once and the data usage is up. Thereafter, I have to send a msg to the host to add more data which is fustrating because I have to msg the host a number of times in a day. If you are gonna rely on your Wifi to do your work or Google the way around in tokyo, then this place is not for you or better still, get your own portable wifi.
2. There was one day we do not have hot water to shower with after a long day outside. The weather was 10 degrees at night. It was horrible as we have to sleep without bathing after the entire day outside. Tried contacting the host but no reply. Host only show up the next day to fix it. No apologies or refund whatsoever. My point is, if you wanna host in airbnb, you gotta be readily contactable when such situation arises.
My take is I doubt I will stay here the next time I visit. I would rather pay more to stay in Shinjuku as it is not as accessible as it seems. Alot of places needed to do a transfer in Shinjuku. The money we spent on train + the stay can get us a good place in Shinjuku.
