Terrific views, comfortable property, and convenient access to grocery and restaurants.
As others have mentioned - the interior is not as updated as some properties, so if you prefer/appreciate interior design you may find the house lacking.
For me, the ample space (both interior and exterior) coupled with the great views and convenient proximity to food and activities, more than sufficed for a nice (though too short) visit to Mellieha. I would definitely visit again.
I think the property would be ideal for a family holiday, and it could pretty comfortably handle a two-family joint vacation.
