Joanna, Andrea's mother, was always available for any questions we had and was incredibly helpful.
We were going to initially use public transportation, but instead used Bolt, which is like Uber. It was a lot more expensive but it was worth it for us. It was very hot while we stayed and the fans Andrea and Joanna provided were a life saver.
Mdina is beautiful. The architecture is stunning and the restaurants nearby all have such sweet and attentive staff. I would recommend staying here if you want a break from the typical super overcrowded bustle of main cities.
There are also a few grocery stores nearby so you can bring stuff back to cook, and since this place has an oven, stovetop, microwave, and toaster, you can save a bit of money by cooking your own dinner!
All and all, a wonderful location.
