Penthouse is not a single room probably illegally built up kitchen on the roof. Safety is an issue as anyone in the building can enter the "elevator" that has direct access to the unit. Also the stairs, again probably illegally built in, are not accessible. I'm a small person and could barely safely go up and down. They offer transfer limousine services and never provides an address because google is filled with reviews identical to mine.

Valletta is steeped with history and the antiquity / scale of the surroundings should not be missed. This unit made for the perfect homebase for a) exploring Valetta proper and feeling like a "local" (minutes' walking to the "city centre" b) jumping down to the harbour for a swim c) exploring Sliema (harbor ferries super close) and d) just getting into/out of the city to explore other parts of Malta. Everyone was super-nice and the unit was special - especially because of the roof deck which really was amazing at night with all of the town lit up around.
