We had a great time in Sliema. The appartment was clean and we had a great view from the balcony. We loved to have breaktfast there, but we could not make coffee because the espresso maker didn´t fit with the oven. Mario told us, that he will bring us a reducer, but it didn´t fit too. So perhaps a coffee press would be better for the next guests :)
The communication mit Mario was fine and fast. He can organize the airport transfer and everything you want to do in Malta.
