Sumario:This is a Reply to the Comment from F. Cinti and M. Boninsegni on our recent work on the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a two-dimensional dipolar system [Bombín, Mazzanti, and Boronat, Phys. Rev. A 100, 063614 (2019)]. The main criticism about our work expressed in that Comment is that we did not explicitly report the two spatial contributions to the total superfluid fraction. Here we analyze our results for a point of the phase diagram corresponding to the stripe phase, close to the gas-to-stripe transition line, and for a temperature below the BKT critical temperature. The scaling with the system size of the contribution to the superfluid fraction, coming from the direction in which spatial order appears, shows that it remains finite in the thermodynamic limit, as we already stated in our original work. This allow us to state that the stripe phase is superfluid at low temperatures. Furthermore, we offer some comments that help to understand where the differences between the results of Cinti and Boninsegni and ours come from.
