We stayed at the Trunk Hotel Yoyogi Park for one night before leaving Tokyo. It was fine for that purpose. The front desk and lounge/bar staff were excellent (booking taxis, making recommendations), the room was clean and comfortable, the breakfast was pretty good (western style) though who serves a bread basket without including butter and jam, and offers only a plain omelette unless you want to apply your two allowable side dishes to the filling? Overall the hotel lacked anything special. Ask for a room overlooking the park - our room at the back looked over an alley, which was noisy at night, and noisier when the trash collectors came through in the morning.
