Hotel Mets is part of Shibuya Station’s quiet south side, with direct access to the JR lines; the location can be confusing at first, but once you get the hang of it, it's convenient. Rooms are modern and comfortable, with the double beds clocking in at a roomy 160cm. JR Pass holders get a 10% discount. The free breakfast is good.
The hotel is especially convenient for the Narita Express airport train, as the platform is very near the south exit.
