I had a great experience staying at Little Japan! The staff are very friendly, and most of them can converse in English. If you are a first-timer in Japan, this is definitely a good starting point to jump around Tokyo, as they are just a walk away from the Asakusabashi station. Ms. Yuki-san personally asked me if I slept comfortably during the night, so for me that is an added bonus; it shows that they show concern and are taking care of their guests.
They also have a cafe in the first floor, so you can order your first meal here, in case you are tired upon your arrival. There are also nearby convenience stores, coin laundry, and other establishments where you can buy trinkets and souvenirs.
They hold small events during the weekends as well, so you might catch one of them during your stay. I had good conversations with the locals (using my broken Japanese, but they are very forgiving on that as long as you try) and some other guests as well. One of their lounge rooms is a tatami-matted floor with all sorts of things you can enjoy while taking a break (gameboards, books in Japanese and English, etc)
One thing not mentioned in their listing is that while they don't have a formal kitchen, they have a refrigerator and microwave, so you can store konbini food in the fridge and microwave them in the morning.
I will most likely come back here! :D
