If you are using a rental car you can park it in the garage for just over 4 euros per day. The car will be safe there. There are lots of clubs in the area but the room is nice and quiet. The room is really quiet because they have double glazing in the French doors. There are lots of really nice restaurants and cafes in the area. The prices charged for food in the area are all very reasonable.
It was a really nice hotel. The people were really friendly and they were willing to help. The a/c is on and when you come in (after the 38 degrees outside) it's really refreshing. The food wasn't anything special but I can recommend ignoring the bacon in the morning as it still has bits of bone in it. There was no beach in the area and all I could see in front of the hotel was rocks. There's a really nice pool on the roof.
We visited Malta, mainly for diving ( wreckages of world war two) and its history. The Vivaldi is at a nice location. Divingschool Divewise is practically around the corner. Other then that there are a lot of cosy restaurants, bars and busstops in the vicinity. We were pleased with the room, breakfast and service.
