My wife and I stayed at Karen and Bob's apt for 6 weeks. They are great; very helpful, wonderful, and respond very timely. They were ready to solve any problems or concerns at light speed. The apartment has killer views of the river and is very close to downtown and the Pearl district, very convenient if you like walking along the river. Yes, there is a train problem, but to their benefit, it is not only the apartment location problem, it is also a Portland problem!! The train crossing is at street level and they apparently must Choo Choo to warn pedestrians and car crossings. Doesn't matter how close or far you are of this location ALL!! Portland will hear it. So we bought ear plugs (silicone), which are also perfect for the swimming pool that the complex has.
Problem solved :). The apartment has everything necessary and is very easy to take care of, very secure and has parking. I cannot thank them enough for letting us stay there and I will hopefully stay again next year.
