Colin was an outstandingly good host, he even came at 23:00 o'clock after us in the bus station and helped us carry our luggage. The apartment is bigger than is shown in the pictures, has 2 fully equipped bathrooms, so the 5 of us could quickly get ready in the morning. He also left us some food as we arrived late at night and were a bit hungry.
By bus it's 30 minutes or less to Valletta and the buses come frequently.
I strongly recommend Colin and his apartment.
