The apartments are very beautifully designed and clean. The location is pretty much unbeatable and the hosts were very friendly, easy to reach and helpful. Overall we really enjoyed our stay, however people are not exaggerating when it comes to the noise level. I have never experienced anything close it. If you have one of the 'downstairs' rooms, you will hear every step, every word of every conversation, every time someone in the other apartment goes to the bathroom etc.
If you're staying in one of the 'upstairs' apartments please be considerate. Don't talk loudly when you come home in the middle of the night (I repeat, your neighbors will hear every single word) and at least take off your shoes when walking up and down the stairs. It's an excellent Airbnb otherwise.
