We stayed at David's place for three nights in April. It was great. You can't beat the location: Coffee shop around the corner, Bourbon Lounge (Pope Hose) around the other corner, Trader Joe's in the back (literally 1min walk!!), And tons of restaurants and shops just as you walk out the door. Also walking distance to Rose Garden and Japanese Garden. There is an excellent old school steak house two blocks down as well if you prefer more formal dining -- RingSide -- with perfect dry-aged ribeye and other great steak, as well as excellent wines. I can spend a month there and just sample more and more restaurants.
Close to Public transportation as well. We paid $2.5 per person at the PDX airport and took the red MAX straight to Providence park, and from there it was a 10min walk to the apartment.
The apartment is not fancy. I don't think you can find "fancy" in that area, buildings are historic and old, and it's part of the charm of the neighborhood. It's a practical apartment with everything you need. Good couch and living room, practical bedroom (bed is on the soft side, if your back requires a firm mattress this might not be the right bed for you), a kitchen with all you need. There is a hair dryer in the drawer, as well as extra towels etc.
And David was super responsive when I reached out for check in and check out, and very helpful and flexible to help us get in early as it was raining. I very much appreciate it.
