The apartment was very clean and beautiful. The internet worked without any problems and to explore Tokyo it's the perfect spot (near tu Shibuya and Shinjuku Station). The area in which the apartment is located is very cute and interesting (small row houses, modern japanese architecture). All in all we had a great stay in Yuka's apartment! The only negative point is, that it's right on the level of the highway and during the night there is a lot of traffic and it might get quite loud..
