If you have a party of five, this is the place to book. Was about $56 USD/person/night which is a steal considering the nice design, sufficient number of WCs, dining/living room, and the mobile wifi was super handy! Also, this place is HUGE as far as Tokyo apartments go.
Took a little bit to find it but it wasn’t difficult. The lockbox that holds the key was actually a nice feature in case you were going out and didn’t want to risk losing the key!
Overall, an excellent place to stay in Tokyo. Very close to the subway, restaurants, the mall. Felt very secure and is in a great neighborhood.
