Great spot and loved the view from the rooftop. We spent some time almost every night up there just watching the harbor in the beautiful evening weather .
Valletta was full of beauty and the recommendations from the host (given in their welcome booklet) were all great.
Michelin Star restaurant , Noni , is just a block away so definitely recommend making a reservation there when you book - we didn’t realize until we already checked in. It we were able to get a table with only 2 days notice so you should be fine.
It should be mentioned that cars will sometimes peel out loudly on the street corner (to no fault of the hosts of course but something to be aware of), the bed is of the typical thin / uncomfortable variety, and be aware the kitchen / rooftop are shared between 2 other rooms .
But small inconveniences in an all in all great stay at a special place !
