Alice & Gabriele are nice people with good intentions but I don't think they are fully equipped and ready to handle problems SWIFTLY especially when you are on vacation and everything needs to be solved quickly disregarding what the problem is.
In our case the A/C stopped working day 2 and a week into the problem they couldn't resolve the issue. Other than not being prepared and ready, the host always tried to involve us with the issue when we where on holiday and all we wanted was peace of mind and little to no involvement in the problem but a QUICK SOLUTION which we didn't get causing huge distress to us and the kids.
