PROs: Aki's place was very clean, has very comfortable beds and is located in a convenient location near a large park, and a central station. It is also only 15 minutes walk from the central area of Shinjuku and there are a lot of really delicious restaurants nearby the Airbnb if you don't feel like going far.
CONS: If you have any flight issues, you will not be accommodated with your booked dates. We added a day to our stay due to a delay but lost a paid day in the accommodation without remorse.
Aki's correspondence was very persistent which may be helpful for many who have issues, however, at times it felt a bit intrusive and there were a few rules that came after the non-refundable booking was made. Such as extra security measures with the addition of passport photos that Airbnb already provides, and your home country's address. There was also the strong enforcement of the quietness rule through multiple messages in which she asked for confirmation of understanding, and the warning that if any issues were had with noise, or if any extra guests were found in the accommodation the police may be called and the guest may be evicted without an accommodation that evening with no refund.. none of this was said in the original listing. We understand that this may be due to a bad experience with parties being held, however, we let Aki know we were using the accommodation for a quiet family gathering of 2 .. as such we felt this correspondence to be a bit inappropriate.
In addition to this, In the accommodation, there is a strange sound level checking device that displays in large red lights the decibels of sound you are making in the apartment. We found this device anxiety-inducing and uncomfortable--it doesn't even say anywhere what level is too high, i think guests should know prior to booking of the existence of this device.
Lastly, the veranda, which was our main reason for choosing this place wasn't very true to the photos. It appears on the listing to be a private terrace, however, it's shared with the entire building and has a curfew of usage between 7am to 9pm, (which also was not listed) It also had no umbrella or carpet, but this might've been weather related.
