Staying at Yoshisato's place was a pleasure. We had a decently sized room (for Japanese standards) with a bathroom/toilet and a mini-fridge. We received towels, toothbrushes, and crispy clean sheets. A very polite and lovely cleaner was tidying up the kitchen and common areas every day, so the place always looked tidy and neat. A pocket wi-fi device was also available to guests upon request, as well as more towels, tissues, and toilet paper etc.
The apartment is conveniently located close to Asakusa temple, market halls, and 3 major supermarkets. (Two of which are open 24/7). It's also about 10m away from a local izakaya-turn-monja place, Tetchan (てっちゃん), which serves the best monja I've had in Tokyo.
The apartment is close to Tawaramachi station on Ginza line, but you can also walk to Asakusa line. It's also about 30 minutes walking to Tokyo Skytree (or 2 metro stops).
I have enjoyed my stay at the apartment, and its convenience. I would recommend it to other travellers looking for a comfortable and private place to stay in Asakusa.
