The stay in this apartment was good, it is situated in a very good place for a tourist - both short and long term. Especially if you like the feeling of a lively and cheerful neighbourhood. Buses to all places, ferries to Velletta and Three cities - all close by. The pool availability was excellent, even in late October. Several small beaches close. If you want to travel all around Malta by public bus then maybe you should choose Valletta for quicker transfer. From Sliema one should usually go to Valletta and then further.
The flat is good size, the terrace excellent. Good communication.
Good luck!
