First off, my wife and I stayed for a month and worked remotely. We also are from Seattle. Will be writing with that context.
WORK FROM HOME: Awesome, awesome, awesome internet. I think I speedtested 850 Mbps down/ ~20 Mbps up. We never had issues even though both of us were on Zoom calls at the same time and I do large file download/uploads. The kitchen counter was a great place to work, and my wife worked in the bedroom on the very wide/long window sill that is basically a desk size.
NOISE: Other reviewers mentioned noise being an issue... we really did not have any issue with this. It is comparable to living in an apartment; you can hear some footsteps upstairs, but not late at night and it was never too loud / inconvenient
HOSPITALITY: Carrie is super friendly and responsive. When we checked in, we noticed there were no window blinds (had been removed last year for COVID) and we wanted more privacy. We also needed more plates / silverware. Carrie was able to accommodate us with this without problem and even installed blinds for us! Very nice!
LOCATION: We lived in Seattle for several years and can tell you this is one of the very nice locations. You are about a 8 minute walk from beautiful Lake Washington where you can see Bellevue and the gorgeous Mt Ranier. There's beaches, small grassy fields, and plenty of places to sit and hang out. Walking through the neighborhood has many hidden short trails and beautiful gardens. Just up the street with a 5 minute walk are some nice shops. Bottle House is a favorite Seattle wine bar and Hi Spot Cafe does a delicious brunch. You are also very close to Capitol Hill for a more artsy / grungy / younger scene. Also very close to the Arboretum and Japanese Garden.
SAFETY: Seattle has a homelessness challenge; it's no secret. Madrona is fairly close to Capitol Hill and Central District where homelessness is worse, and Madrona is known to be a nice neighborhood. I wouldn't leave anything valuable in your car overnight, or any bikes outdoors. No cars were broken on the street during our stay, but it's pretty common for some people to come into the neighborhood late at night and check for unlocked cars. Safety-wise though, it is very safe. There is no violent crime and no homelessness in the neighborhood. Again, it's one of the nicer neighborhoods in Seattle and you should just lock your car overnight and you'll be fine.
COMFORT: Super comfortable bed and 3 heaters to keep the place warm in colder months. Large enough windows for warmer months. Plenty of towels and a washer/dryer available.
Overall we'd definitely recommend this place especially for longer stays! Beautiful location and nice amenities!
