Stayed for a week in January. I never met a host for this trip as it was all organized per instructions per email and the key was stored in a security box and I could open it with the instructions.
If you were to come with big luggage, it’s a bit of travel from Shibuya and walk to pick up the key ans then cross the bridge.
The location was good. It’s located close to the railway yet it wasn’t that noisy. There’s a security system at the entrance so I felt safe on the 8th floor.
One thing that bothered me was the lack of insulation. You can feel cold air along the wall and I had heater on all the time and also bought more blankets to keep me warm. This is generally the case with Japanese home, though the fact that my apartment was at the corner contributed to such a ventilated room.
