We spent 3 nights at Andrea's place and had really great time in Mdina, Rabat, Valletta and other parts of Malta. The place is right in the old city of Mdina inside the fortress technically with a great rooftop where you can watch the sunset. The major bus stop in Rabat is within 5 minutes walk and there you have all the connections you need - to Valletta, to the airport ect. The place was clean, cozy, it was a pleasure to stay there.
Since Andrea was out of town at that time, we met Joanna who was extremely nice and very helpful with variety of information and recommendations. We even had a small water incident with a pipe in the kitchen and she and her husband had extremely quick reaction and everyting was fixed within an hour or so. Thank you, Joanna! :)
