The apartment is really beautiful, and Stella/Oliviero were really helpful and attentive - I turned up over half an hour late because my phone did not have service in Italy but it didn't cause any issues.
Everything was spotlessly clean, and there was even some food available in the mini-kitchen (pasta etc.). Internet works well.
The plug sockets are IEC type L - this is a three prong plug standard, with the prongs lined in a row. If your adaptor is the wrong type, there are adaptors provided for the other common two-prong Italian plugs IEC type C and F standards (IEC type F adaptor was attached to the microwave).
