Jennifer's place was excellent on all respects. Location is optimal whatever is the reason you come to Seattle: attending a conference (as it was in my case) or being a tourist. You can easily walk to the center of town. You should know there is an elevator in the Farmers Market which will take you from the Alaskan way to Pine Street and save you 137 steps.
The apartment is well appointed and the view from the windows overlooking the sound was beautiful! Although facing the Alaskan way, the apartment complex is set back from the road noise was not an issue.
Groceries stores were a bit far (except for the Farmers Market) and you may consider food delivery.
Jennifer was very responsive when I had a question regarding check in process. The staff at the reception was friendly and seemed always available.
Simply put, I would give Jennifer's place the highest recommendation. Unfortunately, I could not rate it 6 stars as 5 stars was the maximum... :-)
