Bathroom Sink Water Pressure

Just moved into new apartment, 2nd floor of a 3 story brownstone (3 single bedroom apartments total).
Water pressure in bathroom sink is terrible. Approx. 20% flow on both hot and cold.
Bathroom shower has good pressure and toilet fills correctly.
Pressure has no change when running hot and cold together so I assume not a valve issue, since I doubt they would both fail with the same consistency?

Kitchen (on other side of apartment) sink pressure is good, dishwasher fills correctly.

Not…
