Other than the size of the apartment which was on the smaller side, it was quite nice. If you're going to be out all day like we were you won't even notice the size. The place was spotless and the washer was really convenient. You could walk to Shinjuku station which isn't a bad walk since you'll be able to see a lot of the sights, although not recommended after a long day of walking. Overall, I'd definitely come back but maybe with just 2 people instead of 3 :)
