Koichi was a great host. The accomodation met expectations.
The toilets AND shower are shared with other tenants.
Please be advised that the wifi fluctuates from weak to strong connection. I strongly recommend that you invest in a mobile internet plan if you are staying for a long time. Also, the window does not stay completely open and the heating does not turn off since the building has a central heating system.
However, despite some minor things, the location is extremely valuable. I was able to walk to every destination I had planned. If you are traveling alone, this is a prime location for a great price!
