All here is optimal! The only way till the station is available in 11 minutes, 7-Eleven right on the next corner, pretty nice neighbourhood and near to asakusa - which I liked the most of the areas here in tokyo.
To communicate with Hisao is easy. He cannot speak English very well, but can explain the important things (what's not very usual for japanese people). So this is the trick: be clear and short. I found it very good.
He was also very flexible with the checkin and checkout times, asked us when we would prefer and was available all the time.
All in all: suberb option to this price!
Thank you Hisao.
