Don't hesitate booking this apartment!! It's absolutely worth your money, and makes your stay in Malta much much much better. It feels like a small villa, with the amount of rooms and floors available. And the 2 (!) balcony's with a beautiful view of the harbour and Valletta were a great addition to our stay here. Especially the fact that the sun doesn't reach them (the apartment faces the east) makes it comfortable to have breakfast or dinner there without sweating your face of.
Lots of small stores and supermarkets around (which are not visible on maps so just explore a bit on your first day) and the restaurants in the harbour had some great and cheap items on the menu. The ferry to Malta cost just 2,80 euro's for a return ticket and buses to all across the island cost 2 euro's and there's a bus stop very close by.
Kitchen comes fully equiped by the way (freezer, oven, everything) and there are also wall adapters if you don't have UK outlet plugs. Would definitely return.
