The space is very unique and quite beautiful in it's own right. One of the cooler places we have stayed given its history. It is damp and musty, but most of that goes away once you air it out and turn on the AC- it wasnt a problem for us, though I do believe some who may be more sensitive or picky could have a problem.
Alberto was great about getting us directions to the space, and there is ample parking on the street just steps away. We enjoyed staying in Senglea and getting to see the three cities as much as we did in addition to Valetta. The ferry is a beautiful 5 minute walk away along the harbor, making this a great spot to use as home base.
Definitely recommend!
