If I could give 6 stars to the location, I would've. It's just less than 10 minutes walk to Asakusa metro station and Sensoji, and I have to pace myself slower due to 2 seniors travelling with us. It's situated in a fantastic neighbourhood, friendly locals, lots of food choices below average price in Tokyo. Nearby supermarket has everything we need. If Asakusa is part of your itinerary, you can go wrong with Kei's place.
