Pros: Quiet, peaceful, walking distance from Akihabara (15 minute to 20 min walk). A station is like 5 min walking distance so after checking in you can easily move around by metro. Mini fridge was a nice addition to keep snacks and some beverages. Toilet seat was heated, appreciated on winter time :)
Cons: No outside illumination at all. Event though Japan is a safe country, the entrance is way too dark, in a back alley in a back alley (yes, double back alley). Place could have been cleaner, easily. After all, we are charged for a cleaning fee. Walls were too thin but most places are build like this so it is not a surprise, but was able to hear other families talking inside their rooms (most likely hear me taking phone calls). Wifi didn't work for me, but I had my own wifi so I didn't bother contacting the host (which I am pretty sure they would have been helpful with solving the issue ASAP). Bed was the most awful spring bed ever. Couldn't sleep well in those 3 nights I stayed.
