Our family stayed at Allen's for a few days. The location is fantastic: very close to the Burke-Gilman trail, the Met Market, and University Village mall. The house itself is on a quiet street, and while there's no dedicated parking spot we never had an issue finding street parking.
The house itself is tastefully decorated, and it had everything we needed--even a pack-n-play and a toddler chair for our little one. There are even desks in every room (and one with a monitor) in case you need to get some work done.
Allen was a great host, and communication was prompt the few times it was needed. I would 100% recommend staying at Allen's place.
