Mathew is a fantastic host and super responsive. He was super proactive when there was an issue with the unit, and he quickly responded and dealt with it promptly. The unit is in fantastic shape, looks renovated, and is at a very good location for local train stations (Mita and Asakusa) and the JR line (Yamanoto). Area is peaceful and you will never have to worry about traffic or pedestrians. The unit even has a separate entrance that is private from the rest of the hotel, giving you easy access.
It is worth noting that the neighbor runs a noodle shop and opens their doors at around 8am by opening their creaky door. It is almost surely to wake you up if you are still around by 8am. Besides that, the unit is fantastic, well worth the cost, and Mathew is an A++ host. Would strongly recommend for tourists.
