Pros: Service, cleanliness, fully stocked kitchen/bathroom, great hosts!
Cons: Noise, old building, 3pm check in
Thank you to Mr Toyoharu and Lynn for the great stay and I appreciate the responsiveness as well as the willingness to give us a 6:30 am tour. Communication was clear and quick and the airbnb met every expectation. If you are coming from the airport they offer to pick you up, incredible service.
Although I knew the trains would be apparent, be aware there are LOTS of crows in the area that will certainly wake you up at 7 am. Fortunately the only noise are from the nearby train and morning birds, it is a quite neighborhood.
The location is also quite far from the JR station (15 minute walk) but if you want to skip the walk the subway is close by. This means that most trips to the other side of Tokyo (Shinjuku/Shibuya) will take at least 40 min from Arakawa.
So, if you plan on going out late make sure you can walk straight and get ready to wake up early.
