We had a very nice trip to Paolos place! The view is amazing and the air conditioning works well in the winter and summer. We were missing a coffee maker, but everything else was there. Valletta was easily accessible by the 1.50€ ferry (tip: the Barakka Lift is included). Grocery shopping is a bit hard as there are only tiny stores around, but we found "The Convenience Store" as a good middle way as it had everything we needed. Bigger shops can be found in a Valletta food court.
