Eric's place was very pleasant. He was incredibly welcoming (he even suggested a good mechanic I could take my car to for an oil change), and his set-up is very organized. He's got the airbnb thing figured out, which is really nice from a guest's standpoint.
He was located in a nice, safe neighborhood that was fairly central to all of the interesting things in Seattle. The only thing I didn't like was that parking was a bit confusing at first, but Eric very kindly allowed us to park in his yard beside the driveway.
I was a bit hesitant about the shared bathroom, but it was never an issue for us. Even though there were other guests there, it worked out well that we were always able to use it for as long as we wanted.
There isn't a private entrance, but Eric provides keys, and is totally fine with you coming and going as you please.
I would definitely stay at Eric's again! Overall, it was an excellent experience!
