Bright and modern, Citadines has compact studios with queen-sized beds, kitchenettes and a sitting area. Some rooms have additional sofa beds (extra charge). It's a bit far from the Shinjuku action, though travellers staying for more than a few days will likely come to appreciate the relative quiet. It has a fitness room and a launderette, too. English is spoken.
