Carla's place in St Johns really is as lovely as it looks online. The bed is, importantly, very comfy and Carla has thought of everything from plenty of up-to-date literature on what to do in and around Portland to quality shower/bath products to a well stocked kitchenette.
Portland has many cool neighbourhoods to explore with St Johns being one so don't fret setting up a base here. Other districts are a quick drive away, and you will want to be getting to them all.
For all the sandwich lovers out there, get yourselves to Lardo. And shout out to Oneonta Gorge walk trail for bringing out the Indiana Jones in me.
