My husband and I went to Seattle to get away for a couple days and had a great stay at Daniel & Danielle's suite. It was nice and quiet and even being in a basement heard very little from the family upstairs. The brief interactions we had with the hosts were lovely.
The couch might be the comfiest couch that has ever existed, (even if I found the bed a bit uncomfortable for myself).
Note: The decor is industrial and very nice but the concrete floors are cold, (who would have guessed?), so I'd suggest bringing slippers or warm fuzzy socks for when you're home after a long day of exploring.
