Great little place near all the good stuff in West Seattle. I stayed here with my friend for three months during a work assignment. It does have air conditioning, which was a real life saver during Seattle's unseasonably warm summer. The kitchen has all the essentials to make a really nice meal. We particularly enjoyed grilling in the back yard. The area is very quiet and safe. We kept the windows open during the entire summer and never worried about it. Laura and Joe were very receptive and available if we needed anything.
It's just a 10 min drive over the West Seattle Bridge to enjoy all of downtown Seattle's offerings. I would definitely consider taking the ferry from West Seattle (Seacrest Park) to downtown. It drops you off right near Pike Place. That way you can see all of the touristy things without paying $15 for parking.
All in all, this place was just wonderful. I would absolutely recommend staying in this adorable 100 year old cottage.
