It is a great apartment. Very well done up, bright and clean.
The apartment was comfortable for the 3 of us. The kitchen was well equipped and the host very kindly had left some cooking oil, salt and coffee. The family mart is a 5 mins walk so you can easily buy what you need. The shower area and the loo being separate is a big help with a group of people. Be prepared that like all apartments in Japan, this is a small concise space and my Son who is almost 6 feet had to manoeuvre his way especially in the loo. But with 2 bedrooms it gave us the space to move around and unwind after a Long day as compared to any hotel room.
The station is a good 15 minutes walk, but be prepared that it is a large station and you walk another 10 minutes depending on the train you want. But it is a very well connected station and most places you can get to directly. The area has some great food options, a good liquor store and a family mart plus lawsons.
A and K are amazing hosts. They were always prompt to reply to any questions and shared interesting information about the area and Tokyo. They very graciously allowed us an earlier check in and let us store our luggage in the apartment till we left for the airport. All in all a good option
