We loved Wendy's place and highly recommend. Ballard is a great area to stay outside of downtown but still be relatively close to all Seattle has to offer. No issues at all with street parking right out front. Un Bien, The Fat Hen, Hot Cakes and Larsen's Bakery were all fantastic places to get food.
The inside of Wendy's place was just as pictured, very comfortable and had everything we needed for our stay. Heated bathroom floor and washer/dryer were a plus for us. Everything was spotless. The yard at Wendy's is also as pictured and very nice and the seating area outside the door is great.
Wendy was a great host and offered several suggestions.
