I think this is a good option to stay close to the Ballard and Fremont neighborhoods, but this is more of a shared unit than not. There are about 4 other units on two floors and you can hear a lot of noise from guests in the hallways and even through the walls of the individual unit.
Vince provides earplugs and an Alexa speaker you can play white noise on to drown out noise. But keep this dynamic in mind if you are looking for something more quiet and private!
