I highly recommend Dirk and Jaq's place when visiting the area of Seattle near the Convention Center and areas nearby. It was clean, comfortable, roomy, and perfect for my needs. I was at a conference and was able to make breakfast to start each day and could easily walk back from the Convention Center to drop things off or for a break. The mattress is fantastic and I am seriously thinking about purchasing one for my house.
Dirk met me there, gave me a tour, and tips for the area. The condo does come with a parking pass and he allowed my friend to use it who was staying in another condo in the building that did not offer one. I feel this is above and beyond what is expected of a host.
As for location, I walked to the Public Market, the Pine/Pike area where there is a lot of shopping, and some other areas off Pike/Pine (I am not very familiar with Seattle) with no issues. As for distance, I believe it took me about 15 minutes to walk to the market.
