[Disclaimer: I lived in Seattle for 3 years, this place is near where I lived and I would live here again]
Rob runs a tight ship! It's located right off the greenlake itself and the 62 bus stops right nearby. Complimentary earplugs are provided for those needing them--since the bus does run often until around midnight and wakes up again around 5:40 AM--which coincidentally, makes a great alarm clock.
The penthouse deck is awesome. It's a great use of space and its got wifi up there and a peaceful view. At night you can really see the stars, at dawn and dusk it's just amazing.
Typical for Seattle homes, there's no central AC--but plenty of windows and fresh air and fans--and Seattle has the best tap water this side of the cascades [glacial runoff is tasty]. The shower works well and is nicely appointed.
Also note that you aren't too far from Ballard's trendy eateries, Fremont's Freakshow or Wallingford's homespun buffer near the U-district. This location is a 15-min. trip to downtown; and never more than 45 minutes back since you can always take anything but I-5 on the way back. Even if you don't have a car the aforementioned 62 bus literally stops outside every 15-20 minutes; Uber and Car2Go are other mobility options.
The downstairs is "shared" although I never saw anyone, but beyond having to know 2 door codes, you will never tell.
One last thing--Rob will charge you 25$ [+ shipping] if you forget something --and you happen to want it back--that means he will ride his dirt-bike* through a plate glass window, hit up the post office and FedEx, swing in from a helicopter and get the overnight package out before deadline to get it cross-country before a holiday weekend. [*partially dramatized event based on a real story]
To be honest our trip was great, but the "oops I forgot my laptop" moment while stuck in traffic to the airport was made a thousand times better by Rob and his prescient policy. While not a highlight of the trip this is definitely a highlight of the caliber of individual you will be working with--that alone is worth it. The location is tops, the maintenance and orderly process is highly functional--and the people you will be working with are of high repute.
