Natsuko's place was very cozy. We felt right at home. It was clean, easy to find, closed to many train stations.
We were 2 adults with our 2 yrs old toddler and 6months baby.
She was very helpful, recommended really good restaurants and things to do.
The most wonderful thing for us was she knew we had a 2yrs old with us, so she provided some little toys for him which he greatly enjoyed.
The only negative point is we didn'r have the pleasure to meet her.
I def. recommend her place for a nice, welcoming stay in Tokyo.
