Had a pleasant stay at the sharehouse in the 6F. Min is easy to communicate to, and responds almost instantly! He was clear with directions, and very helpful. I arrived a few hours later at night when I landed, and he was so gracious to wait for my arrival to help with my luggage up the stairs (elevator was down at the time), and to check in. Location is very central, about a 12 min walk to shinjuku station, and lots of restaurants and the heart of shinjuku accessible within minutes. The only con is that there is only one shower shared by everyone. However, the hot water was made up for it. Would highly recommend if wanting to stay in the heart of shinjuku.
