Convenient and very inexpensive. It's very easy to access other parts of Tokyo. Even though there's quite a few beds, there wasn't any problem with noise.
Les points faibles : Personnel et service et confort de la chambre
Cheap hostel, expect the bare minimum
Unsupervised co-ed dorms led to a fellow male guest trying to harass me for a kiss. If my bunk could be locked, I would feel much more comfortable sleeping, but the anxiety I felt lent itself for an extremely uncomfortable experience at Hostel Azalea. Additionally, there was no secure area for me to keep my belongings. Since the door didn't get locked all night, theoretically anyone could have came in and stolen my stuff.
However, the showers and beds were clean. Expect what you get for your price here.
