Claire's apartament is in a superb location when it comes to travelling with public transports - there are numerous bus stops within just a few steps. It's not the quietest location with St. Julian's being the "party district" so nights can get loud. Fortunately, the windows block the noise sufficiently and there's AC in the apartament so you should be okay even in summer - I know we were. Grocery shops, bakeries, cafes and even a small bear are also very close to the apratament. Overally, it's a great place to stay when you're visiting Malta, don't hesitate to book it if you get the chance :)
