The place was perfect for our needs. It was easy to get to via the trains and it was only a short walk from the Hatagaya Station. Mitsuko provided really great instructions (with pictures!) on how to find the property which were a great help. There are lots of shops and restaurants nearby so once you get there, you don't have to go far to get what you need.
The place itself is small, but perfect for 1 or 2 people. It has everything you need for a short stay!
