When Eyal goes to Alex and Pia's hotel in Tel Aviv to pick them up, the hotel seen in the establishing shot is the Renaissance Hotel. However, the next shot of them actually walking out of the hotel has them walking under a sign and past security barricades that all say Sheraton Moriah Hotel.
When Eyal runs out of the party at the villa, his shirt-tail is out, which is unlikely. When he arrives at Manachem's hotel it is still out when he leaves the car, but tucked in when he runs down the hotel hall and talks to Manachem in Manachem's room. Then when he returns to the villa, it is out again.
When Eyal visits Menachem's Berlin hotel, a shot down its hall reveals that all the rooms have Mezuzot on the doorframes. At the door to Menachem's room, the only room without a Mezuzah, there is a clearly visible unpainted patch from which the Mezuzah had been removed just for that shot. A Mezuzah is a small box filled with bible passages (Deuteronomy 6:4-9 and 11:13-21). Jews put them on the doorframes of houses and other buildings. Their presence reveals that the filmmakers used an Israeli location for that hotel instead of a German one.
