This place is amazing. I highly recommend it. It is one of the best airbnbs I have stayed in. It is very well designed with lots of great touches. The only ‘bad’ thing I have to say is that while Tim had 3 types of coffee for you to choose from, there was no sugar to sweeten it with.
It was not clear from the pictures, but the outside patio has plants all around it so even though the place is in the back of the main house, it feels very private.
In regards to the location, I would recommend having a car, this is probably more of a general Portland note than specific to this place. There are pockets of places but the pockets are spaced apart. There are a couple of buses near the apt that get to Downtown area in 15-20min but we enjoyed the East side of the river where the car is more helpful more.
