Honestly, quite late in leaving this, but someone asked me for a recommendation in Malta, and I had to come back to leave a review! I was in Valletta in December, and had a fantastic time at Valletta Lucente.
The accommodation is in a fantastic central location in Valletta, and is above the ceramics shop also owned by the family. It is a very short walking distance from St. John's Co-Cathedral, and a brief walk to major bus transport hubs which made it easy to get around the rest of Malta.
Hosts were lovely and helpful, and the the breakfast every morning was freshly made.
