Marc was absolutely great and greeted us at a very good location outside the central station.
Absolutely brilliant apartment that made the trip so much better and easier. Located in an amazing location. A few minutes walk from Dam Square, and ton of shopping facilities of all types around.
The apartment is very calm. The only noise you'll hear is yourselves, maybe some footsteps from the neighbours (which is not at all loud) and of course outside. There will be some chatter/music being heard outside the window, however this is only in the day.
The apartment was very clean ad complete with all amenities mentioned. WiFi was great and did cause any problems.

********
The only issue (not entirely an issue for my friend and myself) were the extremely steep stairs going up to the apartment. Would not suggest this apartment to any individual with disabilities/pregnancy/walking problems.
For a young fit person the stairs will not be a problem and can serve to be a small game every time you need to encounter it.
