2nd time staying there. Convenient location, large room and suitable for family with kids. Not cheap at all but don’t expect any services like in other Japanese hotels even the budget ones. For instance, rare to see staff, no cleaning throughout stay for a week (including to clear your own trash), no tooth brush provided and no luggage storage after check out.
I am a family of five with small kids and I had an afternoon flights so the apartment can suit my needs. However, if my kids are old enough to stay in a separate room, there are many other better choices around with cheaper prices and basic services.
