Maria's place is amazing. It's very clean and well-appointed with a great record collection and superb literature. The beds were comfortable, the garden and porch are really nice to hang out in, and we felt relaxed and enjoyed ourselves the whole time.
The house is located on a quiet street in Fremont, yet only a short walk from lots of great restaurants, bars, and cafes.
Maria is a gracious host and a great communicator. I'd definitely stay at her house again, and wouldn't hesitate to recommend this place to anybody visiting Seattle.
