My wife and I spent about a month and half at this apartment. For two people this place can be a bit small if you plan to stay that long. Parking can also be a little tricky. However, that's probably the only drawbacks that I can think of. Other than that, it's a great apartment in excellent condition and in a great neighborhood - there are a lot of nice cafes (La Parisienne is by far our favorite there :)) and restaurants around within few minutes walk, Space Needle is about 10-15 minutes walk, the center (with Pike Market) is about 30 minutes walk, or you can go by the monorail which has a station just near Space Needle. By the way, the monorail is really few meters away from the window, but it goes so silently that you won't ever notice it unless you are looking into the window and waiting for it :) Kevin promptly responded to all our questions and requests.
Overall, it was a great experience to live there, and if you plan to stay in Seattle for few days or even weeks I would highly recommend this place.
