Nice place..!! It's such a pleasant place to stay while you in Tokyo. It location near many convenient stores (like family mart, 7eleven), and also near the station (just walk about 5 minute to Asakusa tsukuba station). And you just can walk to the famous shrine Sensoji and Don Quijote Asakusa.
Mr. Hiromasa such a great host, he always quick response my message. His place so clean and tidy. It's a small apartment but it quite enough space for me and my 3 friends. The wifi signal was very good,, and you can bring the wifi modem while you explore Tokyo, it's really help me because my Japan SIM card was not working.
I think there was nothing to complain about, and i definitely will stay here again if i have plan travel to Tokyo next time.
