The best part of the apartment is the view. It is amazing at any time of the day.
The location is good if you are OK with a 50min bus ride to the happening places like Valletta and Sliema. Malta buses are never on time, but they are an option. The bay, the boardwalk, and the surrounding areas of the apartment are great for beautiful walks and hikes. It is an easy walk to the Convenience Store, but must take a bus or drive or Uber to the larger grocery stores as the roads are not walkable to Mellieha (shame they didn't make sidewalks for such a beautiful road!).
The apartment is spacious with high ceiling. The layout is very good. Both the kitchen and living room face South, so in the winter, it is lovely.

As some reviewers mentioned, the apartment amenities can definitely use a update/upgrade. The management is responsive, but the "infrastructure" or the management budget is limited, so there is only so much can be done.
