Had an absolutely wonderful experience with this rental. My husband and I were traveling with our 15-month-old and the apartment couldn't have been more perfect for our needs. In addition to all the basic amenities and a few extras (lovely deep bathtub for soaking, portable wifi devices, detailed and extremely useful house instruction manual, Apple TV), the many child-friendly touches made our stay unbelievably easy and hassle-free. Tia provided a baby crib, high chair, and bucket of toys in addition to a few diapers, toddler snacks, and baby soap and bubble bath, which far surpassed any expectations we had and allowed us to explore and sightsee without having to worry about logistics.
Tia went above and beyond in her duties as a host, anticipating and addressing issues before I even had a chance to ask. I mentioned that my family was on a layover weekend in Tokyo in the midst of an international move, and she suggested luggage storage at the airport, accommodated our early arrival, and was helpful and communicative throughout our stay.
The apartment itself is spacious (for Tokyo) and well-equipped. The beds were comfortable, bathroom clean and stocked with extra towels and linens, and heat/AC in good working order. The neighborhood is quiet and residential within walking distance of downtown Shinjuku (about 15 min on foot).
Overall, this was a wonderful experience and I wouldn't hesitate to recommend Tia's place to anyone looking for a great launching pad to see Tokyo, particularly families traveling with children.
