Klesta is an incredibly wonderful host. She responds super quick and couldn't be more helpful (she arranged for a taxi to fetch us from and take us back to the airport - so easy!). The apartment is fabulous and it's in a great spot - 5 mins walk to the ferry to Valletta, and even closer to the bus from Valletta. Sliema is ok if you like shopping and new build sea front; personally I liked Valletta, the Three Cities, Mdina, Rabat, Mosta etc better but it was lovely to stay in such a luxury apartment (and the views from the balcony of Valletta are fabulous!) Be aware though that there are building works at the moment right next to the apartment and work starts around 7:00 am.
