Very nice apartment, in a good location so it's quite easy to find ! It has a rooftop which is really nice to enjoy a dinner in fresh air :)
And since Sliema is really hot in summer, the flat is full of fans so don't worry about it.
Location : Sliema is a really nice place to stay, not far from St Julian's (20mn) if you want to go partying, and not far from Valleta. You can also go swimming there and you have a lot of supermarkets, shops and restaurants !
