My experience with Kit it was very good.
She has a lot of skills that helped a lot.
I'm Brazilian and went to NYC just on vacation but wanted to improve my English in different way, with private classes introducing things day to day and mixing with tour around the city, visiting gallerys, coffee shops, running away from traditional format of classes.
I chose and proposed this format because was my vacation and I had just two weeks to enjoy he city and improvement as much as possible my English.
She is a very good teaches, helpful, easy going and intelligent. But I know that was a challenge for her.
I think that she can improve this format, but with some adjusts It's a very good option to who want to scape of traditional classes.
