We stayed at Edward's apartment for 8 days and we had a wonderful time there.
The flat is very spacious and full of useful amenities.
It's located in the heart of vibrant St. Julian's, where you can find a lot of entertainment, including clubs, restaurants, cinemas, cafe's and shops. However you won't experience any noise. It is very convenient to catch a bus and easily get to most of the parts of the island.
Edward is a very helpful and responsive host, we would strongly recommend staying at his place if you are heading to Malta. You will not regret it :)
