We absolutely LOVED our stay in Malta. The pictures Alberto used depict the apartment perfectly. In fact, we firmly believe that the view from the apartment is the BEST view in town. If you want to relax and simply enjoy the island, you can do so right from Alberto's apartment :)
We also loved the location. Senglea (also knows as Isla) is an up and coming quarter in Malta. It still has the authentic feel to it, as most of its inhabitants are local. In fact, at night you can hear the children playing football (soccer) down by the waterfront, families united around the table eating at the restaurants below or strolling along the sidewalk.
We loved taking the ferry to Valletta or strolling to the other side of the waterfront to Bormla where the most exclusive yachts are parked. The fort on the other side isn't open yet, though will be a "must see" once it is. The ferry ride is only a 10min ride to Valletta (keep your ticket once you get to the other side as you can take the lift up to downtown for free). Worth getting there just before noon to see the firing of the canons, though it is quite warm at that time. Consider going to the "Malta Experience" show as well. Another must see is Mdina, especially around sunset.
Our 12yr old enjoyed a "swimming with the dolphins" at Mediterraneo, though difficult to get to if you don't rent a car (we suggest you rent a car for at least 2-3 days to get a good feel for the island).
If you're there on Sunday and have rented a car, we suggest a trip to Marsaxlokk for a delicious meal of seafood (we had a nice plate of calamari). You can buy fresh fish on Sunday there when the fishermen bring their catch to the harbor.
As for our host, Alberto was extremely helpful and hospitable. He was very attentive and always available for any questions/ needs we had. The whole holiday was a real delight!
