Excellent place to stay. Location is about a 5min walk from Yoyogi station and a 15min walk from Shinjuku station. Place is surrounded with eateries that open late at night, so there's plenty to eat at even 10pm.
One downside is the venue doesn't have an elevator and the stairwell is very narrow (about one person shoulder width). If you're bringing heavy or bulky luggages, keep that in mind.
