Mami's house is very pretty! It's modern, techie, flowery fragrance-full, nice and neat. It's located near Musashi-Koyama station, which is not far from Meguro. You can find couple of convenience stores so close to the house; it will be helpful when you have a plan to send luggage via Yamato TaQbin, you can just drop your luggage there.
If you are couples, Mami's house is just right. You can find anything you need there, with such pretty displays & arrangements. Mami was really helpful and lovely to talk with. Something you cannot find in 5-star hotels! :D
