Best location possible. A block from King's garden, close to Nyhavn, footsteps from restaurants and bars, and 2-3 blocks from multiple grocery stores.
Maria was great. She responds to every communication within just a few hours (if not minutes). When I mentioned that our 4 year old needs mid-day naps--she went out and purchased and installed black-out curtains. Really amazing responsiveness, thoughtfulness, and everything you would want in a host.
If you are a light sleeper, bring some earplugs. There isn't any drunken revelry, but if there is a loud group walking by or street sweeper, you will hear it. My wife (light sleeper) had no problems, but you might want earplugs just to be safe.
