With the exception of some controversial areas, this hotel must be the cheapest and the most cost-effective accommodation in Tokyo.
So, I would recommend to you that you should stay here during your trip in Tokyo. Then, you'll be able to spend more money on other activities like food, sightseeing, night life, etc.
1980 Hotel Tokyo

Last month, I stayed there for 4 days
Although this is a capsule hotel and the fee is unbelievably cheap, it lived up to my expectations, clean enough, kind enough and comfortable enough!
To women, don't worry about that. Floors are separated by gender. So, you'll never see kinky men.
Based on my experience, it seemed like customers were half Japanese and half international. Hence, you don't need to speak Japanese!
Furthermore, the location is very attractive because it's very closed to the Asakusa district, just a 15 minute walk from there. I was even able to walk back to the hotel from Tokyo station when I missed the last train. It took "just " 2 hours.

(I've been hooked on capsule hotels for more than a decade)
Perhaps, the next global trend for the hotel business will be capsule hotel, as its number has increased internationally.
