We stayed in this apartment for 4 nights and had everything we needed. It even had a kettle, which, being Brits and needing our tea, we were very pleased with! The bedrooms were spacious and comfortable. The apartment is in a great location for a lot of the city. We didn't have a car but we were able to walk to all the main places very easily. This included the Clipper ferry terminal where we even walked from with our luggage (although uphill!). There are lots of restaurants within walking distance too although the apartment is nice and peaceful (it's on the inside of the block so looks out on to the gardens).
Communication from Ashley was friendly and quick. We had a problem with the tumble dryer, that I fear was user error, but Ashley was very quick to deal with it, even on a Sunday. Check in and check out were both very straightforward.
All in all, I'd be happy to stay here again if I were ever to be back in Seattle!!
