The place is located quite near the centre of Shinjuku, around 10 mins walk from JR station and easy to find. Quite some Restaurants near the bnb so you don’t need to worry if you check in late.
It got all the basic thing we need though it was a bit tight for 3 people. But since we only stay there during sleeping time, it’s not a big concern to us.
Overall very good accommodation I will recommend.
