My wife and I (travelling around the PNW from the UK) made a conscious decision to stay in downtown Seattle where we met up with our daughter who had travelled down from British Columbia. As a base for seeing the sights of Seattle the location of this apartment couldn’t have been more central! Pike Place Market is literally across the road and we were able to walk around some of the key sights and neighbourhoods within a 20-30 minute walk. The return journey occasionally involved a taxi/uber, but in any case, there are plenty of options for a nightcap/meal within a block of the front door (be aware that a lot of restaurants only open until 8pm or 9pm)
It does get very busy around this area (see above re: Pike Place Market), but the apartment was cosy and had everything we needed for our 3 night stay (and Seattle Coffee Works was right next door, providing a great coffee first thing in the morning!)
