we had pleasure to meet our host Seiji even if he was busy with his own work, checkin was easy because the door was open with the keys on the table.
The area is very quiet and not so far from Sakura-Shimmachi (about 6 or 7mn), and the station is at 4 stops for shibuya. So it's ok :-)
the appartement is ok, may be it would good to improve the mattress and provide sheet for the beds, mattress and pillows ?
overall a good stay at Seiji place, a charming host, I recommend this airbnb.
