Dirk and Jaq were really nice. I didn't see them but they answered quickly my questions and they did all they could to make my stay very enjoyable.
There is a guidebook with all you need to know for the appartment or for visiting Seattle.
The appartment is clean, comfortable and close to the downtown. I never took metro or bus during my stay: you can walk and go easily to the downtown or the most of the attractions in Seattle.
I recommend Dirk and Jaq's appartment and if I come back in Seattle, I will definitely go back in their appartment.

Thank you for all Dirk and Jaq
