Great value for the location! Closest station is Senkawa which is very accessible as you can easily transfer to Yamanote line via Ikebukuro. It will be a bit of a walk from Senkawa station to the house but this was not a big deal. Lots of convenience stores around but I highly suggest buying from A-colle, it's a discount store within the neighbourhood (much cheaper than konbinis!) The house is very clean and will have everything you need. Shower and toilet are shared but I never really had to queue as there are plenty enough for all guests.
