Seems like 7 night minimum required.
Flights priced on bookaflight.co.il and alice.co.il (if you listen to Israeli radio you know who alice.co.il is) - both read OTAs not something fake
Alice is a real OTA, but they have handled refunds extremely poorly: massive delays, no way to contact them, demanding a fee to process the refund, etc. I think one of the founders or a relative also recently got caught embezzling funds from the business. I would not use them anymore.
