Nice place for a piano player who wants to recite before their big day in Ikebukuro. The place is listed for two ppl but it is the best suit for one unless you want to sleep really close to each other, which is not a bad thing sometimes.
The building is close to the station and easy to fine. There is no elevator in the building, and people with heavy luggage could have some issues.
The piano itself is in excellent condition. The place is next to the railway but thanks to the soundproof room, we could get a good night's sleep without interruption by the train noise.
The kitchen has enough equipment to prepare a decent meal. However there is not enough space to sit down and eat for two people, so keep that in mind.
