I and my friend stayed at Dirk and Jaq's place for no less than ten nights. The place was great and convenient. I met Jaq on a few occasions and she was a very kind person and hospitable host (she rapidly replied regarding questions we would have, in my case on how to find specific spots in the city). The place was very neat and the facilities were fresh – the restroom/shower was very clean and the kitchen was good for when you wanted to make yourself some breakfast (not included, but there was no problem in buying stuff and keep in the fridge). Wifi worked flawlessly. The location is also great – it is very close to the International District/Chinatown station, where you'll find connections to other parts of Seattle as well (buses, as well as the light rail which goes to/from SeaTac).
