Stayed at Carla's place for 3 weeks while doing a course at the Royal Jubilee. Great location, close to key buses to downtown. Longer but walkable distance to Willow Beach and Oak Bay area. There's a grocery store 10 min walk away. Her place is clean and had all the basics you'd need for a longer stay away from home. The bed is also quite comfortable!
In regards to the noise level, yes the floor is a bit thin so you can hear people moving about above. They have young children so it quiets down by 8pm or so and doesn't really get loud again until 7am ish. I was up getting ready before 7 am anyways for work so it didn't really bother me.
