Yuki's place was spacious, very clean and with full amenities. We had a very comfortable stay and the beds were particularly comfortable so we slept very well! Lots of little eateries and supermarkets close by. Just a note if you have big/heavy luggage that it is a bit of a walk from the station which is Nishi Shinjuku Gochome not Shinjuku so you will have at least one transfer to get to major attractions.
