The apartment is spacious, clean and well situated being a short (less than 10mins walk) to the Sliema to Valletta ferry and about 15-20 mins to the sunbathing/swimming part of the seafront (through town). There is a really good bakery within a short distance to get bread for breakfast. The street is very quiet even though it is only one street back from the sea front and felt safe. The apartment is on the 3rd floor ( there is a lift) with a locked outer door to the apartments as well as the apartment itself. The kitchen was well stocked and we had plenty of towels etc. provided. The balcony was small and can only really sit 2 people.
We used the taxi pickup to and from the airport (20 euros each way) arranged by Marissa and this worked very well.
Overall we had a really good time and I would recommend the apartment.
