Franco's apartment is very very central! I could walk anywhere in Valletta, 5 min to the bus station (it will take you all over the island) and 5 min to the ferry to silema (party area)! The street is very quiet so we could sleep at night!
The apartment is what I call a vacation apartment: the shower is very small, but you can make do while in Malta! One note is that you will have to share the terrace with the other guests at the apartment above!
We loved spending time on the terrace drinking wine :)
The wifi is excellent!
I would go back to this apartment and to Malta!
