Zaito is clean and simple. All you need for a short stay in tokyo. Also it is just a short walk from Oshiage station. Which has express lines to the two airports. While close to cultural spots like Asakusa and places like Akihabara, it is quite a long train ride to the spots in the west of Tokyo like Shibuya/ Shinjuku.
