We enjoyed staying at Brad and Becca's place, everything was clean and tastefully decorated, the beds we found to be very comfortable.
Access to the rest of the house and the front door is via the guest area, so if you've no problem with that then you're fine.
The creative and informative map of Portlands highlights is fantastic! We actually enjoyed exploring the neighborhoods closer by, like Hawthorne, than downtown or the old town.
Brad and Becca always responded super-quick to our messages via the app, too.
