Kyiv's most happening hostel is this gleaming 100-bed affair superbly located at the bottom of Andriyivsky uzviz. An attached cafe-bar, a basement kitchen, a laundry room, key cards, bike hire, and daily events and tours make this a comfortable and engaging base from which to explore the capital. A few doubles (some with bathroom) are available in addition to dorms.
The expert, English-speaking staff are a great source of tourist information, and they run fun tours to Chornobyl and other excursions out of Kyiv.
