Hiro and Misako's studio apartment was a lovely and cozy place for a couple. For us (two adults and two kids with three luggage and 4 bags) it was a bit too small. There will be stairs to climb but not too bad. Check-in was easy and there was an iPad for registration. The beds are very comfy, the kitchen is tiny but organized. It would be great if basic cooking stuff such as salt and oil were provided. All instructions were clear and Hiro's response was always timely. Location wise, there was a 7-11 shop just around the corner and there were plenty of eating places and restaurants nearby. As we took the JR train line every day we had to walk to the subway train station (not far), take the subway train first then the JR train to Shinjuku.
