We stayed 7 nights in the apartment of Airin. We were a family of 4. The apartment is an easy 8 minutes walk from the Sangenjaya station. Nearby you’ll find 7 Eleven, Family Mart and even a grocery. A lot of Japanese restaurants are walking distance too. The apartment was so clean and complete with all you may need (towels, soap, shampoo, washing machine, clothes rack, microwave, hot water pot, etc.). Airin was so easy to contact and she would reply right away. We’ll definitely stay in Airin’s apartment again next time we’re in Tokyo.
