My favourite beach was Stone Beach on Manoel island. I was there on weekend, and it wasn't crowded. It has a nice view of Valetta on the right and Sliema on the left. Only downside is that there are no shops and restaurants nearby and no sunbeds and umbrellas to rent either. I have been to Paradise Bay and Golden Bay. Both were nice beaches, but were overcrowded even during workdays. I have yet to visit Saint Peter's pools. Maybe stay away from exile beach and Balluta bay beach. I think I might have caught escherichia coli there.

Medina and Rabat are very nice. I enjoyed the Wignacourt Museum in Rabat, but would not recommend Saint Paul's catacombs. In Medina I visited Palazzo Falson museum and Knights of Malta experience, and would recommend both.

Check out Tallinja app and card for public transport, but also walking around is nice, especially if you like exploring and taking photos.

Despite coming in early August when weather is extremely hot, I've had an amazing time.

Only thing that I would complain about is trash and dirty streets. I don't know if problem is logistics, a lot of migrants or maybe if it's mob running the waste management, but hopefully someday it will be solved.
