Great location. Great communication with Darcy, the kitchen is well stocked.
There are homeless that congregate around Pioneer Square (and all along 3rd avenue) but they never bothered us (we stayed for 4 days altogether-3 days in late July then another night in mid August).
The A/C unit worked well and kept the apartment comfortable during the Seattle heat wave.
There is music at night - my husband is a light sleeper and earplugs worked fine for him.
