Great place in shinjuku! It’s not too far from the station (about a 7-10min walk. if you have a lot of luggage though, it could be a bit far). The place was well prepared and had everything we needed for our short stay in japan.
Just a note: the place is on the 3rd floor of the building. Once again, not a big deal but if you have very heavy luggage, it might be a bit difficult.
