Location: the place is 5 mins walk from Shiinamachi Station of Seibu-Ikebukuro line, and you can transfer to EVERYWHERE in the city pretty easily.
Accommodation: I stayed in the shared room, it was quiet, clean and came with an air-conditioner. The room was cleaned every day even when no one is checking out. The only thing is that it might be a bit tiny for travelers with huge luggage.
Service: How should I put this? Shota-San is so kind and thoughtful, to my understanding it is way beyond the meaning of service. Every morning they provide the guest a free cup of coffee and whenever you want the most authentic and original recommendations, Shota-San is the guy! And he communicate with great English skills too!! So travelers please also try to follow the Japanese house rules at this place, even though I know sometimes it takes a while to get used to.
All in all, a stylish place with heaven-like hospitality! Fun fun fun!
