This house is absolutely beautiful and is located close to Ikebukuro Station, one of the biggest stations in the Tokyo area. It's very convenient to get around Tokyo. However, it might not be the most kid-friendly or elderly-friendly place if you're traveling with your family. It's close to many love hotels and a bit far from the station (~10 minutes). The stairs are also a bit steep inside the house itself, so it might be tough for grandparents or older parents. I think it would be best for a family of younger people or a couple looking to have a house to themselves.
Despite these things, the host was EXTREMELY helpful, kind, and responded very quickly to all my requests (and I had many!) so I really appreciated it. The house was very clean and well-maintained and looked just like the pictures. Recommended!
