Extremely spacious 3 bedroom flat with amazing view and great location to Sliema and ferry to Valletta and so many restaurants and bars just steps away. Marielle was super helpful in arranging transportation to and from the airport and explaining things in the apartment.
We were visiting in August during extremely hot weather in the entire region so this may not be a factor for all seasons but note that there's air conditioning in the living room at one end of the flat and the bedroom with en suite bathroom at the other end. With such a spacious apartment, the AC doesn't reach the two other bedrooms in the middle very well. There are fans, which helps, but when it is 95/35 degrees around the time you're going to sleep, the fans or opening a window won't help that much.
There was also some issue with electricity in the unit and the elevator, possibly related to the extreme heat, so it's possible that this affected many places on the island at the same time.
I would also encourage you to think about the location with respect to where you think you'll spend most of your time. During our 5 day stay we went to nearby Valletta exactly twice, but we made the drive up north many many times.... to go to Gozo, ferry to Comino island, and to go to Popeye Village. It's 30-40 minutes of pretty challenging driving for someone not very used to extremely narrow roads. I wish we had looked into accomodations on the other side of the island so we could have made one or two trips to Valletta but been closer to the Gozo ferry and other places.
