Keio Plaza Hotel
Yes, I would recommend this hotel as the views are spectacular. The room was very comfortable. The hotel is huge and it has a pool. There is a 24 Hour store nearby, Natural Lawson, with all kinds of things to buy for breakfast if you don't want to eat in the lounges. The metro is very close too and a huge electronics store. The Shinjuku neighborhood has everything, it is lively and there are always people on the street.
