Dirk & Jackie are definitely Super Hosts. Communication was very good and the place had everything I needed for my stay. Check in was easy. (They even quickly sent me the charger for my Laptop that I left behind upon departure.)
The apartment is perfectly situated between downtown and Capitol Hill so there were plenty of restaurants and nightlife in the area. It was a 15 minute walk (at most) to the Pike Place market. The apartment is a corner unit with trees on one side of the building so you get light and privacy.
If I find my self in Seattle again, I would definitely book this place. (Or try. The more people discover this apartment, the harder it is going to be to book it!)
