Good location in a residential part of Nishi Shinjuku with a 7/11 very close by. About 7 mins walking to Nishi Shinjuku Gochome metro stn although be aware that at night you may have to walk from Tochomae stn which is a bit further (maybe 10-12 mins). Nice coffee shop nearby called Counterpart Coffee that we frequented (the flat only came with green tea pods). The bathroom is indeed tiny but we were OK with it, and all in all, found this place fine for the value in Tokyo.
