The place is very good, very clean.
If you walk 13-15 minutes you will get to the Uguisugandi station, a JR station so if you buy the JR pass, it is very helpful because there are 2 important lines for this station (Yamanote line is one of it).
Also if you walk around 7 minutes you will get to Irina station (subway) which is also very helpful.
there is a mini super market 5 minutes walking. The hostel has no kitchen but it has a microwave
And mini fridge.
I have to say that the house does not have the best location but it is good and for the price is really good.
Japan is safe so you can walk at any time.
Enjoy Japan!!!
