I've stayed in Seattle once a year for the past 8 years and Eytan's place is in the top 3. The lower floor is about 300 SF and includes a large TV, a full kitchen and a dining table for 3. Also available is a full size washer and dryer which adds a nice touch for a the traveling worker since it allows me travel with less clothing overall.
A wrap around stairway leads to the bedroom on the 2nd floor. The bed is suspended by threaded rods. As a professional structural engineer, I can say that the bed was sturdy you could easily put two people on it without realizing it was suspended. Although the bed is close to the ceiling, you can easily sit up right without any issue. Directly over your head is a window that allows fresh air in at night. Like most places in seattle, the home is not air conditioned however, I've only ever seen one AC in all of seattle during my years here.
The bathroom is full size and there are many different hair products to choose from.
Windows are plentiful throughout the space as well.
A parking spot is also included with the rental however, you really cant fit much more than a medium sized sedan such as a Toyota Camry. As a daily driver in NYC, parking wasn't a challenge and you can do it in one move, but I can see it being a challenge for some.
There is a family community around here, and in the summer time, its likely you'll sleep with the windows open. You may hear some kids playing or planes getting ready to land but it wasn't really bothersome and expected in a dense urban city.
The GPS gives you directions to a gate that leads to the house, but the driveway is actually around the corner. It wasn't exactly obvious and I'll admit, I did not read any instructions on how to get to the driveway, I just got lucky and found it. If its not in the instructions, perhaps including a google map aerial view with arrows pointing on how to get to the driveway might make it easier for others.
Overall, this was a very pleasant stay. The house was clean and well equipped. I would absolutely stay here again!
