In general, it was fine.
However, the cutlery was very dirty, so I couldn't use it, and the electric kettle was broken.
The bedding or towels didn't smell, but they weren't clean either.
If you don't eat and just sleep, you can use the family unit.
Communication with the owner in English was good, and the response was fast.
Check-in is self-check-in, and there are 24-hour convenience stores and marts around the apartment, so it's very convenient.
