This is what it cost me in Canadian funds:
Cost of procedure including deposit was $5,775 - $300 refund since I did not require a stent = $5,475 (13 000,00 PLN - $1 000,00 PLN refund)
(This included 9 nights - double room at the Hotel Arena, our breakfast and the transfers to the airport and appointments - Doppler ultrasound examination / Vascular surgeon consultation - MRI examination and neurological consultation)
Airfare was $3,517. I believe there are cheaper rates if you book earlier and you don't mind a few transfers.
So we spent a total of $8,992 + our food, drinks and sightseeing.
We paid a deposit of $1,450 Cdn before leaving by bank transfer (all this information will be sent to you) and we paid for the balance by credit card at the clinic before I went in for the procedure.
