Narrative:

We were executing the flight portion of a 61.53 flight review and wings phase. We performed a simulated engine-failure north of [a private] airport; including a low approach to the traffic pattern. There were no other aircraft in the pattern or the vicinity. Winds were light and variable. A go-around was executed at 200 feet AGL; and we climbed back to 4;500 feet for our return to [our home airport]. As we leveled 12 miles northeast of dvt; we received a radio call on the deer valley north tower frequency; from an unidentified station; asking if we were on frequency. We acknowledged; and the voice advised us that [the airport we trained at] is a private airport; and that landings and low approaches are not permitted. We acknowledged that transmission.I am aware that [the airport] is private. We did not land; only executed a training low approach and go-around. There is no airport/facility directory entry for [the private airport]; and I do not believe that low approaches can be prohibited by the airport operator. There is no restricted airspace at that airport.it is not clear whether the transmission came from dvt tower or from someone on the ground at [the private airfield] transmitting on the dvt tower frequency. In any case; the caller did not identify. We will avoid this airport completely in the future.
