The apartment was lovely. Our hosts had prepared a coffee maker, french press, toaster oven and kettle. Really helped us in the morning. The grocery store is across the street near the subway station so very easy to buy food. Our hosts replied very quickly to any questions we had.
It was only 5 minutes from the subway and 25 minute walk from harajuku and shinjuku. Shinjuku-gyeon is only 5 minute walk away. Disney is about 40 minutes by subway. If you have a kid interested in fire trucks or helicopters, the fire museum is only 5 minute walk away.
Our only issue was that floor made a lot of noise when we walked. Luckily no one lived below us. Overall an awesome apartment in a great location for us.
