My stay at Laura's house went really well. Several of my friends instantly wanted to move in as soon as we walked in the door. Laura clearly took some time to bring this craftsman home back to life and also bring it up to date. It was sort of like being in a HGTV "after" reveal. The house was clean and well decorated and the backyard was perfect for a small BBQ with a perfect fire pit.
The home is about a 10-15 minute walk from the Mississippi district with lots of bars, restaurants, and shops. You do have to pass over a highway to get there, but it's really not a big deal (and sort of fun). It's hard to get a handle on the neighborhoods of Portland because things are changing so fast there, but I felt safe walking around during the day and at night.
I never actually met or spoke to Laura. I believe the scenario is that she is the owner, and she has a tenant living in the basement that takes care of the property. Either way, this wasn't an issue at all. My group briefly met the tenant and she seemed very nice. Her communication through Airbnb was also great (quick, kind, accommodating).
Overall, a great experience and I would stay there again for sure. It's not the cheapest place in that area, but it's beautiful, comfortable, and sleeps 6 comfortably in 6 different beds (or 9 in 3 queens, and 3 twins) so that's a big bonus. Thanks!
