Suzuki’s apartment is a very nice place exactly as described. Less than five minutes walking from Komagome station, it’s in a quiet residential neighborhood on the first floor of an apartment building. It has a washing machine (detergent available), a stove, a bathroom and a main room that includes a small table, a small TV and the bed. Towels were available just like shower gel/shampoo/conditioner, ironing board/iron (which we did not use) and kitchen equipment (which we again did not use). Everything was perfectly clean and tidy. On top of that, there is a mobile wifi router that can be taken along during the day which makes e.g. navigation with Google Maps very easy.
Suzuki’s communication is very quick (responses in <5 minutes) and uncomplicated. On our checkin day, the cleaning company was finished early so we did not even have to store our luggage in a locker at the train station but could access the apartment early.
Komagome is a nice place, some restaurants and shops on the way to/from the apartment and about 30 mins by train or less to all major attractions in Tokyo.
All in all: very nice stay and we would definitely come back.
