I enjoyed my stay here for the most part. There's a TV in the room as well as a desk, and I could do some cooking though there was limited space. The bathroom was quite small and there was some mold unfortunately, but I managed. I mainly had two big concerns, one being the dirty laundry room. The dryers don't do a very good job either, so I spent a lot of money doing laundry. The other concern is that the dishes included were not clean at all, so bring some dish soap.
The neighborhood is very diverse, with lots of Vietnamese and Nepalese restaurants and shops nearby, and of course Koreatown is a short walk away. Since the apartment is near Okubo Station, it's a convenient location but can be noisy due to the sound of the train. However, this did not bother me, but I know it may bother others.
The communication with the owners is very good. When I had a concern about the wifi or asking for an extension, the issues were resolved immediately.
I would consider staying here again for a shorter time period. The location is perfect for anyone who loves an international community.
