Lisa's place is fantastic - great spot, roomier than you would think, and so close to everything on Alki beach. The rooftop was fantastic and where our group spent most of the time. 100% would be back again!
Only thing I would keep in mind is the road right in front of the house can be loud at times during the evenings, so the front room with windows open can be a bit loud - bring some earplugs or play some white noise and you'll be fine!
