My stay here was cozy and comfortable. I would very much recommend staying here!
The Pros:
The bunk beds are the biggest I have ever seen, very spacious even when sharing between two people.
The location is right next to a convenience store, and a short 10 minute walk from the train station, so it is rather easy to get around.
The value! While your stay will only have the bare essentials for your comfort, considering the price point compared to prices in the rest of Tokyo it is very reasonable.
The Cons:
While it is technically not a hostel, it does have the feel of one and operate in a similar fashion. I love hostels, but I wish the space had somewhere, such as a common space, to sit and mingle.
The room itself is VERY small, with just enough walking space between beds for one person. It's totally livable and not a huge deal, but worth mentioning.
