Everything went a bit wrong.
To start with, the host double booked my first day. So she booked for me to stay in a nearby place. This is already annoying, but to make it worse, I was only given one day notice, it was Jan 1st so had to checkout at 11 with a hangover, AND she booked me in a dormitory. I don't stay in dormitories because I snore and I have too many valuables. So this was totally unacceptable. She did apologise by refunding one night's stay, but it was still a major problem.
On top of that there were other issues. The bed was uncomfortable, there were loud AC fans right outside my room that kept me awake, the internet totally died for hours at a time. The rooms were also quite poorly ventilated I think so did smell a bit.
On the upside, the location is good. 8 min walk from Akiba, close to a station that goes there so good connections. Was provided with a nice selection of snacks (might have been part of the apology) and the rooms felt very secure.
