Amy is SUPER-sweet and helpful! This is a great bus to stay in in a great neighborhood with a great host! The bus is cozy and comfy. As Amy will tell you, it tends to lean towards the outside temps, and environment. So, if it is sunny outside, leaving the curtains open will be a good way to enjoy the warmth. If it gets chilly during the evening and you like things toasty, even when you get out from under the covers and awesome electric blanket on the main bed, use the heaters she supplies. They work nicely and quickly.
There is a small refrigerator (not sure the size), so plan grocery shopping accordingly. Maybe take a look at everything, first, before getting food. Also, if you plan to cook in the bus, plan for meals you can cook or leftovers you can heat up in her toaster oven.
Local transportation is pretty good at great prices, but depending on how much time you have in Portland, what you want to see, and your purposes for your trip, you may want to rent a car for certain excursions, plan outings to places in close walking distance to one another, or plan for an entire day's outing to include travel time.
I LOVED the index card box full of tips and drawings from people who have stayed here (on kitchen table). Neat to leave a little note there or to make up a new phrase using the magnetic word strips placed on the roof of the bus (in kitchen/living room area)! I also loved Amy's eclectic style with the fabrics she used for curtains, etc. Again, AWESOME bus and stay! : D
