I had originally booked just a couple nights here, and ended up staying almost two weeks. Wonderful, clean, new and fresh. Spacious sleeping bunks with thick, comfy and supportive foam mattresses. Best beds I slept on over a month of traveling in Japan. Really friendly and helpful staff. Excellent cafe/bar on bottom floor, fun hip vibe, even people from the neighborhood spend time there not just hostel guests. The Kagurazaka neighborhood is an excellent hideaway, quiet residential neighbourhood just minutes by subway from all the biggest and best locations in Tokyo. Showers and a huge bathtub, clean bathrooms, laundry, common room with refrigerator, rooftop patio, cool events, everything a traveler could want.
This was the nicest stay of my whole trip, including a number of private hotel rooms that cost considerably more. If you want better than this, you want a luxury hotel suite, and you'll pay 20x as much for it. Take a leap and stay here, you will love it!
