As a Malaysian Muslim girl who is crazy over anime, this is the place to stay. Location-wise, it is as advertized, just a 15-minute power-walk away from Otome Land & Sunshine City. I didn't take any train rides for the first three days coz everything I wanted was accessible by foot. The Otome Map came in real handy here. Masjid Otsuka was just a few minutes walk away from the house. The khariat there were very friendly & I spent a good four hours there chatting up with them. The JR & Metro trains were ever convenient and just minutes away from the house, on which I went literally everywhere (Mt Fuji for one far-off example). Oh, but there is so much more to this lovely abode than just its location: it's the hosts, Tahir-san (Kiyoharu-san) & Rukaiya-san (Chie-san) that made my short trip to Japan an amazing one.
Rukaiya-san had kindly received me near the Metro Shin-Otsuka station on arrival, and led the way to her house & to the Green Room. This private room was just the right size, along with a sink and a stove with cookwares. The sejadah was a nice touch, as I didn't bring mine.
Tahir-san and Rukaiya-san had also invited me for dinner with the family & another occupant from AirBnB. They were very engaging and we talked for hours about everything under the sun. (Please do continue reading up on One Punch Man!) Their sons even made takoyaki for us. As a Muslim, I really appreciate the chance to try out real Japanese food that is halal. Them food were so goooood. (PS: I didn't even touch the numerous Halal food reserves I brought along from Malaysia, which all became Tahir-san's then-dubbed emergency rations. Halal-compliant food was literally everywhere in Tokyo, just know where to look at the ingredients.)
Rukaiya-san has been kind enough to show to way to literally everywhere; Animate Ikebukuro, Masjid Otsuka, Tokyu Hands, even to the supermarket for a lesson on how to choose Halal-compliant food. The icing on the cake was when Rukaiya-san helped lunge my numerous luggage to Sunshine City with her bicycle. She even went out of her way to make sure that I would get on the right shuttle bus for my flight home.
In conclusion, the hospitality of this family has absolutely made my trip to Ikebukuro & Japan all that more memorable. Thank you very much, Rukaiya-san & Tahir-san.
TLDR: The location is amazing. The hosts are even more amazingly friendly & engaging. Definitely coming back to Ikebukuro & staying here again. Thank you for the memories!
