This is a nice, functional and well-located apartment to explore Valletta and the entire island of Malta. The apartment suits up to four people, but I would not recommend to stay there with more than two people, as the additional couch/bed is not that comfortable.
The kitchen is very well-equipped: there were drinking glasses, coffee cups, wine glasses, a kettle, fresh kitchen towels and dish soap. In the bedroom, there is a huge wardrobe, and in the bathroom, you will even find a washing machine.
In the winter, it gets quite chilly in this apartment (houses in Malta are generally not insulated), but there is a small heater, which helps a bit.
The best aspect of this apartment is its location: it's a five to ten-minute walk away from Malta's main bus terminal, so it's great as a base to explore the entire island. All the interesting sights of Valletta, such as the Barakka Gardens, So John's Cathedral, Republic Street can easily be reached on foot within five minutes. The ferry to the neighbouring town of Sliema is also not far away.
All in all I would recommend this apartment as a great basis for young people to visit Malta. For us (friends in our 20s) it was a good place to stay and sleep at night-time.
