We had a great time at our long term stay at Jean Paul's place. He was incredibly friendly and accommodating, and we absolutely loved the loft. The location can't be beat as well. It is a short walk to the sculpture garden, Space Needle, and Belltown restaurant area, but just far enough away to be secluded from the late night noise/crowds. I'd recommend it to anyone staying in the area.
As a note, while the loft was ground floor with a street entrance, we always felt safe and didn't have any problems.
