Summary: Not recommended for those traveling with kids/teens or anyone wanting to use the stay to socialize. A potentially good choice for older adults/elderly traveling in warmer months and/or that don't care about being able to control warmth in the rooms.
Pros:
There are many to be fair - a cute older place with some fun furnishings near Wallingford which is pretty convenient to a lot of areas of Seattle. Despite the street parking I often found an opening right out front which was surprising. Nice shower with rain can shower head and separate detachable handle. 2 legitimate separate rooms with large beds via a master bedroom and a loft area and a lot of extra sleeping in open areas (murphy bed in living room, an additional futon upstairs in the loft, etc.) Functional kitchen with small stove, microwave, ~3/4 size fridge and eating area. The beds were extraordinarily firm which was fine with me.
Cons:
1) A "House Agreement" sets the tone: you're under threat of a "negative bad noise review" should bad behaviors such as "loud bursts of laughter", "foot pounding", "banging luggage" or "TV volume past 20" (which was broken anyway) occur. The agreement firms things up by saying if you can't comply with the host's demands for library-like quiet they'd have preferred you not stay at the property. As a result, even traveling with only my 16-year old daughter I was very nervous throughout. As a result can't recommend for people with kids, teens, twenty-somethings or really anyone other than middle-aged adults or elderly.
2) The temperature of all rooms is unmodifiable/host controlled. Radiator heat is seemingly available, but all controls were disabled and controlled only by the host. When I contacted the host about how to raise the heat there was no reply. Some rooms were colder than others but IMO a lot of guests not used to cold climates - particularly women - would have been cold in this room (my daughter was freezing throughout).
3) Less importantly the TV was completely non-functional. I didn't come to Seattle to watch TV, but wanted to check out Sunday football. Contacted the host, again, no reply. Actually the only reply I received from the host throughout was when I asked about what they preferred done with our dishes.
