According to the New York Post, Porzingis has rented an apartment in the same Manhattan building that Anthony used for workouts recently.
The Post reports that Porzingis has rented units for himself and his two brothers in the Sky building on the west side of Manhattan.
Anthony designed a full-court gym in the building and used it for workouts earlier this summer before joining Team USA.
It's unclear if Porzingis and Anthony plan to work out together at the gym in the Sky building (the court is part of a fitness club open to both residents and non-residents). But Anthony helped ease Porzingis' transition to the NBA last summer by working out with him at the Terminal 23 gym in Manhattan.
Porzingis also has a home in Westchester, near the Knicks' practice facility.
