I stayed in Aoca Tokyo for 9 days during my business trip, and the place met my expectations. The location is well situated from Haneda airport as it only costs about 3,500 yen max to the Airbnb by Taxi. You can also take a local bus service from Haneda to Omori JR station for 280 yen, then walk about 8-10 minutes. If you do not have large luggage, this is a good option. There are many inexpensive ways to get to this Airbnb. If you are taking a taxi, the street in front and back of the Airbnb is too narrow for a taxi to park, therefore, you will be generally dropped off closer to the place and walk about 20 seconds.
Ohmori/Sanno area has lots of inexpensive restaurant options, dry cleaners, and convenience stores. First few days of my trip, I stayed in the area and got everything I needed locally. Walking to the station is very straight forward, and takes about 8 minute, wished it was closer but it's not bad.
Room was big enough for one or two, and equipped with everything I needed. One draw back for some people is that the proximity to the train tracks. You will hear trains running constantly and the alarm of the track crossings during heavy business hours. The train, however, will stop running after 1am so you can get some sleep if you are hearing sensitive. For me, I got used to the train noise very quickly, and by the second day the noise was not a problem to sleep.
Overall, I enjoyed the stayed at AOCA Airbnb, and I recommend to many people except ones that are too noise sensitive.
