I know this is a pretty broad question but I am planning my second trip to Portland this August. Last time we were doing a west coast road trip and only stayed in Portland for one night outside of the city (we found places to stay as we went so we didn't stay in the best area). This time we will be renting a house and staying in Portland for a few days before driving out to Bend and Crater Lake. We will have a rental car. There will be four of us and we'd like to be able to walk to do somethings maybe get dinner, a drink or coffee in the morning but it wouldn't be awful if we needed to drive to see some of the different areas.
Two houses are in the Irvington area, two are in Richmond area, and the other is in the Westmoreland/Sellwood area. Not sure if any of these are in an ideal spot but it's hard to tell what a good spot would be. Last time we were in Portland it was an awful rainy day and we spent most of it in the Japense Garden and the remainder in the Nob Hill area walking around and looking at shops.
Any advice/information would be appreciated. Thank you soo much!
