Mayumi and Natalia are great hosts! They received us at the train station and took us to the apartment in two cabs, which was amazing, since it was our first time in Tokyo and we were completely disoriented after an 11 hour flight. Their hospitality was outstanding! The apartment is just a few minutes walk from the subway station, but a 20 min walk from the main train station at Shinjuku (if you have JR pass) and from the main Shinjuku area, however its a pleasant walk to the apartment. The apartment itself is extremely clean and organized. It is spacious (3 stories) and was very comfortable for a group of 5 adults, although I imagine it can get crowded for more than 6-7 adults, since the beds are clustered together in some of the rooms. Beds are comfortable and the apartment has all the amenities you may need, including a wifi hotspot that you can use when touring the city. Kitchen is well equipped with all the basic necessities. Overall, we had a great stay and would recommend this apartment to everyone!
