We (2 adults, a small Chihuahua) had a wonderful holiday in Villa Serraglie.
The house is built and equipped to a high standard, deserving the name "Villa". It seems that the owners live in the left part of the house, but we didn't see them at all during the two weeks we stayed there.
The very large garden in front of the house, visible from the terrace, is beautifully landscaped and well-maintained. The terrace also features lovingly tended large terracotta pots with flowering Canna plants. The garden behind the house includes the pool surrounded by numerous olive trees. The vast property is completely fenced, so we didn't have to worry about our small dog running off. As mentioned in the description, the villa is not located directly on the lake. However, if you are prepared to drive to all destinations, you will have no problem getting around in all directions. The villa has its own driveway with an electric gate and garage door (all operated remotely), allowing you to drive directly into the private underground garage without having to get out of the car. From there, a staircase leads directly to the living/dining area, providing convenience regardless of the weather and enabling a cool departure in the car. It's a level of comfort that we would wish for at home as well ;-)
As mentioned in other reviews, the air conditioning doesn't cool very much. We were able to compensate for this by using the high-quality retractable mosquito nets on all windows. Especially because the bedroom has windows/doors at the front and back, you can sleep very breezily and without mosquitoes. The internet speed (around 15 Mbit/s) was usually fast enough for HD movies on our Apple TV.
We really enjoyed our stay here. We highly recommend Villa Serraglie to people with high standards.
