We review recent developments in the study of the AdS/CFT correspondence in low dimensions, focusing on the construction of AdS3/CFT2 and AdS2/CFT1 dual pairs in massive Type IIA string theory. We start discussing the AdS3× S2× CY2× I solutions to massive IIA supergravity with N=(0,4) supersymmetry constructed in 1908.09851. We review the 2d CFTs dual to these solutions, together with their defect interpretation as surface defects within 5d fixed point theories living in D4-D8 bound states. Next, we discuss the AdS2× S3× CY2× I solutions with N=4 supersymmetry constructed in 2011.13932. We discuss the superconformal quantum mechanics dual to these solutions, that we interpret in terms of line defects realised as D0-D4 baryon vertices in 5d Sp(N) fixed point theories. We review a particular example in this class of solutions, constructed through non-Abelian T-duality with respect to a non-compact isometry group, and discuss the possible embedding of a 3d black hole geometry constructed long ago via non-Abelian T-duality within this solution.
