Hi Mr & Mrs Sliema2,
I don't suppose you'll read this until you return but what a guess!
Well the reason I chose Siggiewi is that it happens to be one of our favourite villages and you're quite right that it gets mega hot during the Summer.

While we were there last August, we were walking round the very pretty back streets (in the shade!), and noticed a house renovation taking place. The Maltese owner that was doing the work invited us in and we had a look around. Work was at a very early stage and he was showing us the cellar rooms (that had been previously filled in), that he was excavating out. I can't remember the name of the street but I'm just wondering if this is the property your friend has purchased?
With its large open square and magnificent church, Siggiewi is a typical Maltese village and a place we shall always visit especially now you've mentioned the 10 bars! Please let us know how you rated them - location, drinks, food etc?
