It is a newly renovated nice flat with 2 bedrooms (of which one has it's own bathroom) in a good location in Malta, around 2km walk away from St. Julian's. You can reach bus stops in 5 to 10 mins or ferries within around 20-30mins. The pool looked nice and was good to have nearby, even though we never had a chance to use it because we either were exploring the island or already went to swim at some cliffs or beaches. A big grocery store (Lidl) is around 15mins walk away, some smaller stores can be reached within 5 mins.
Communication with Karl was very good, there will always be small 1-2 wrinkles during a stay, but Karl made sure to quickly and efficiently offer help with the questions I threw at him. We all enjoyed the flat and the location and we would definitely book a listing of Karl again if we return to Malta.
