We loved our staying at Jolanda's!
The comunication with Jolanda, even before arriving to Malta, was always super easy. She arranged a transfer to pick us up at the airport and waited (her son actually) for us to arrive home, although we only arrived past 12pm.
When we arrived home we had some bread and other goods to eat the next morning, that was super great and we loved that nice touch.
The house is amazing, super spacious and in the perfect area. Really close to the beach but also super accessible to other areas of Mellieha and other cities.
Our only complaint is that our staying was too short, we wish we didn't have to go back!
I totally recommend Jolanda's house for your staying!
