Negative Covid 19 PCR Test for entry to Spain
 

Has anyone or know of anyone who arrived from the UK after 23rd November and had to produce the negative covid 19 negative PCR test document. How much did it cost in the UK to have the PCR test and how thorough were the Spanish airport authorities on checking these? I know it's been only one week since Spain announced this requirement but would still be interested to know. TIA.
