The apartment had about everything we needed. The apartment as simple and had all the basics, but also had some extras that made it feel even more comfortable: white noise machines that blocked out external sounds (there was a party around the corner one night), a Roku w/ signed in Netflix account, and a plush comforter.
You won't find a more careful and accommodating host on AirBnB. Tri went about and beyond in communicating how to use the apartment (the locks are a little complicated), gave useful lists of restaurants and grocery stores nearby, provided quality recommendations from previous guests, and tips on Seattle quirks like they're recycling system and the excellent quality of their drinking water. A few days in Tri checked up on us, and provided extra towels when we said we were running low.
The locations was central and convenient. A 15 minute walk north on 12th (which has interesting restaurants and shops in it's own right) is the artsy and fun Capitol Hill. A 15 minute walk south is the International District, with an abundance of authentic Asian food and shops. There are also quite a few restaurants right outside the apartment - the Peleton was our favorite. The 12th & Jefferson bus stop is right around the corner, providing cheap and convenient access to downtown via the 3 or 4 route. If you're taking the train in from SeaTac, be sure to grab an ORCA card at the station, its makes all public transit easier and cheaper!
