A great option in North Central Seattle. The separate entrance and easy parking really makes it feel like your in a private house, albeit one without a kitchen (you do have a microwave, coffee pot and a mini fridge). Host was super nice and very quick to respond to any questions I had.
Only thing I would mention (nothing to do with hosts) is the height of the unit. This is a basement unit and as a result the ceiling is a little low. At 6'3" I was fine but anyone much taller than me might be uncomfortable. Also the back ⅓ of the bathtub (farthest from faucet) has a lower ceiling, I didn't realize but the "step up" due to the tub was just enough that I did hit my head. Still fine to use the shower but I thought I'd warn others, silly as it sounds I didn't think of it.

All in all this is a great option, at a really reasonable price. Your close enough to I5 and 520 that it's easy/quick (for Seattle) to get downtown or to the east side. Lake City (neighborhood it's in) also has a ton of cool local options for restaurants and entertainment so you may not even need to go far.
