The apartment is very comfortable and air con efficient. The terrace is wonderful- fabulous view. Kalkara itself has little to offer - very residential with a couple of not great cafe/bars and a bakery. But a 10-15 min walk brings you to Birku/Vittoriosa with has some lovely waterfront restaurants and where you pick up the water taxis to Valletta. We did not meet Nicholas although he always answered my messages very promptly.
