The appartment was very nice and clean, spacious and well prepared. The view of the Duomo is indeed spectacular. However, the downside was the enormous heat in the appartement as the heating could not be shut down - it actually was set to "off", but it kept on heating... In addition, the 7/24 service was not reachable, nor did we receive an answer when I left two voicemails on that number's answering machine = no service at all! I did have two urgent questions, but no one to turn to - and this for an average night's price of over EUR 500.- This is not the way I can recommend to anyone to chose Sweet Inn.
