Jeff has done a good job describing the unit. The bedroom is probably bigger than I thought it would be while the rest of the house seemed a bit small. As he says the extra bed is best for small children. The only issue I had was the the heat/AC was controlled by the main house. Overall this was not much of an issue during the winter but may be during a warm Portland day.
The resident dogs have a big bark but are real friendly. Street parking is not an issue and the neighborhood is quiet.
