Super nice host!
I arrived at the place early just wanting to leave my luggage but ran into Reina and she let me checked in before the suggested time. She explained the facilities clearly before leaving me the keys.
The room is spacious for two and adequate for three, with a tiny open kitchen which you can prepare breakfast and cook simple meals on your own with the kitchenware provided. One can enjoy the view of Skytree and chill out at the well decorated rooftop too.
The place is nicely located in a quiet residential neighbourhood, with a 24-hour bargain supermarket and many convenient stores nearby. Within walking distance to Tokyo Metro station of which exit has escalator going up and down. This is very important when you are carrying suitcase instead of backpack because not all exits of all stations have these facilities. Another bonus is that there is a direct train going to Narita Airport and it only takes around 50mins. Cheaper and faster than Narita Express.
