Such a nice place to stay! It was big enough for two (I think it'll be able to afford 3-4 ppl, 4 may be a little stuffy though), very close to seibu-shinjuku(3-5min walk) and shinjuku station(7-8min walk), neat and cozy. We were in short of detergent, and Midori directly sent us one by her tailor! Awsome! And there are even some popular restaurants around. Ramen house, pepper lunch,.. Etc. I strongly recommend this place lol!
