I often stay at Dan and Jackie's place when visiting Portland. Each time, they have made me feel more than welcome, and they go to great lengths to ensure guest comfort.
I very much enjoy the Studio. It's a great size - not too small, or too large. The kitchen is quite useable, and the living area is warm and cozy.
The gas fireplace (on its own thermostat) more than keeps the studio warm, and adds a great deal to the ambiance.
It has it's own parking space, which is super-convenient.
All in all, it's one of my favorite places to stay in Portland!
