The apartment felt brand-new and was much nicer, but smaller, than it appeared in the photos provided. Great location in a quiet but not too quiet neighbourhood with great restaurants and bars. Subway was a short walk away, about 10 minutes and about 10 minutes on the subway to Shinjuku and Shibuya. Convenience stores open 24/7 close by. Amenities provided were great as well. Paper thin walls as seems to be the standard in Japan, though.
Thorough instructions to find the apartment and a self check-in procedure that worked fine besides the passport and personal details part: Japanese law requires that you provide detailed personal information and a copy of all quest's passports. Me and my girlfriend were asked by Ogawa to provide this information ahead of our trip. We did it as is recommended by AirBnb, using the AirBnb platform: personal details were sent through messages on the AirBnb website and photos of our passports through the AirBnb-provided e-mail for the host. I asked Ogawa to please let us know if the photos of the passports were not received.
When we arrived at the apartment, however, we found instructions to present this information again using a tablet located in the apartment. Weird and unnecessary, we thought, since we've already done this - but fine. However, the tablet camera was so crappy that it was impossible to take a photo of our passports with the text readable. We gave up after about 10 tries and thought that this must be why we were asked to provide this information beforehand. Irritating, but no big deal.
A week of our trip has passed when we receive another message from Ogawa asking us to provide this information yet again. Really irritating, as we've already done this not once but twice, and also specifically asked to please let us know of any trouble with the photos ahead of the trip.
Furthermore, we certainly did NOT appreciate the threatening wording of parts of the message: "If you don't provide I am afraid you will get punishment from the govement as well". Moreover, we were asked to send this information to a third-party e-mail adress, a practice that is not recommended by AirBnb. Sending passport copies and personal details this way felt... weird.
We did however and asked for clear confirmation that everything is okay this time. Confirmation came a few days later. This kind of ruined a few days of our trip as we worried and were anxious about this.
