My fiancé and I had an excellent stay at Mimi and Toney's. The room had everything we needed, the shared bathroom was well stocked and well kept, the kitchen island full of snacks was a nice touch. Their place is located within easy walking distance of all of the Nob Hill/23rd Ave areas, and the taco truck next door was excellent.
It is right next to a busy street and freeway, so there is a bit of traffic noise, but this did not bother us at all, though neither of us are light sleepers.
I would absolutely stay here again if we return to Portland.
