The Appartement is nice as on the photos and the view is amazing but they have serious issue with the sewage and they know about it as others mentioned this before. As for the other guests surprise surprise they could not fix it. It simply stinks like crazy and the main problem is that one of the bathrooms is connected to the main living room and that make it stink everywhere. With lots of Air you could reduce the level to endure the smell. Again the Appartement is nice compared to others but the smell kills you and need lot of alcohol to overcome that permanent smell :-) at least the nose is an adaptive organ that helps
over time.
