Our stay at Libby's was really great! The communication was fantastic, Libby answered all of our questions very quickly (e.g. places to eat, transportation, things to do) and even helped me to find a doctor for my son when he wasn't feeling quite well. The place was spacious and clean and we had everything we needed.
You can hear the highway (it's pretty close) and planes from SeaTac (it's a ten-minute drive there) but it didn't disturbe us very much.
Would stay there again :-)!
