John was an excellent host, responsive and helpful. there is pocket WiFi too which is great to take around Tokyo if you don't have a Japanese SIM card.
the room was cleaned, however is in a bit of disrepair. the walls are a bit stained, the bathroom is very old and quite dirty in the vents with alot of rust and generally worn out. however, for a place so close to Shinjuku and with Korea town right next door it's a decent price for Tokyo and was comfortable enough.
even though the building was a bit old and run down I'd still stay again, as John was a great host and it is in a convenient location.
