We had a thoroughly enjoyable break in Valletta, and Umberto's apartment was an ideal base. It's in a central location, minutes from the major sites and with good dining options all around it. The apartment itself is well presented and well looked after. It is spacious and has good kitchen amenities, though we hardly used them, choosing to eat out. The checkin / out process was excellent and the transfer that Umberto arranged to and from the airport was really efficient. I can't think of any negatives, everything was good.
