If you plan to stay around Shinjuku and looking for one or two night, it is ok. But for longer stays i would recommend you to look for somewhere else.
Nothing special, place is crowded and sometimes can get loud since there are no rules or so.
Place is well connected, 10-15 mins on foot to two major stations.
The hosts seemed very friendly but receiving the weirdest and the rudest message of my life after leaving the place took all that friendliness away.
After my personal experience, i can easily say that this is a place i wouldn’t stay again.
