The house was nice but the distance of walking to/from the trains made getting around the city more difficult. The huge list of 'House Rules' and additional work on the guests weren't ideal. You pay for a cleaning fee and yet still have to clean the dishes yourself or get charged a fine. You also need to organize all the trash, recyclables, burnable etc. I don't mind doing that but there were no separate trash cans to help make this happen so I had to use a bunch of plastic bags to do this which made one part of the house useless taking that space up.
The second floor is strictly just for sleeping so it was a tad bit of an inconvenience and the stairs like in most Japanese homes are small spaced, very narrow/steep. The lack of ability to have fresh air inside the house is a bit rough, very dry in the house when you turn on the heaters. The neighbors were very loud and would wake me up in the middle of the night/early mornings, if you are a light sleeper like me it's a bit exhausting.
