We were very happy with our stay! Extremely clean space 3 blocks from Nishi-Shinjuku-5-chome subway station. Very convenient central location that will easily get you to main attractions in Tokyo like Meiji Shrine, Yoyogi Park, Tokyo Fish Market, etc. Also important, you are 15 mins away from Sendagaya International Clinic, a great English-speaking clinic.
Everything in this home is new and modern. Separate ACs in bedroom and living area with remote controls. Comes fully stocked with kitchen tools, cleaning supplies, and toiletries. There is a washing machine and the balcony has hanging rod for drying clothes (Japanese homes do not have electric dryers). Space is small, but this is normal in Japan. Pack lightly, do laundry every few days, and you'll be fine. The location is fantastic and you will feel like a local. There are lots of food options within walking distance. My favorite ramen shop is Hijiri ひじり屋西新宿店. Inside they have English menu. Get the Tokyo Ramen with special pork! There are several convenience stores open late -- the white bread and egg sandwich from Lawson is amazing.
Aki always answers quickly every time I message her. There are thoughtful touches in the home to make you feel more comfortable. She provides plenty of umbrellas, and bike locks on the 4th floor railing for storing and locking luggage if you want. She even provides pocket wifi, which is a life saver for using G***** Maps to navigate subway system.
Aki is a great host and we would definitely stay here again and recommend to everyone!
