I stayed at Steve & Nelga's for 30 days. They were great! Hospitable, friendly, very accommodating, and responsive. Their house is kept very clean and is very well-maintained. It must have been remodeled fairly recently; the carpets, walls, paint, bathroom, all look brand new.
I'm pretty sure the neighborhood dates from the turn of the century (190x), but you'd never guess that from how well-maintained the houses are in the area (including this one). It's apparent that the people around northeast Portland are very proud of their homes; they're the most beautiful I've seen on the west coast.
The location is great too; a small plaza (with Whole Foods and some restaurants, cafes, bars, etc) is only a block south-east, and the fantastic Alberta street is less than half a mile north. I found it very easy to drive and park around the city; I hear the public transportation is pretty good too but I didn't try it during my time there.
