I recommend this Airbnb, it is very well located in Sliema. Close to shops by foot, or possibility to move by Taxi, via Bolt or Ecabs, which are very fast and inexpensive.
The airbnb is very well laid out, very functional and quite spacious. There is even a small balcony to drink coffee outside in the morning.
There are lots of nice things to see in Malta like the Blue Lagoon, the Blue Grotto, swimming in Cafe del Mar etc. This appartement is well located between La Valletta for a walk or Paceville to party.
Above all, Simone is an exceptional host, who welcomed us very well, she is very professional, and very kind. She has plenty of great recommendations to discover on the island.
