Midori place is very great.I booked the room for 6 people and 6 night.The place is convenient for transportation and comfortable for stay too.Her place is West side of Shinjuku that quite but not boring because you will see a lot of restaurant and shop all the way to her place.I like it more than East side.Her place is very clean and great to come with a group family ,friend or couple.
Take about 8 mins from Shinjuku station and 5 mins for Shinjuku-Nishiguchi .I will definitely come back stay Midori place when I am go back Tokyo again.
