l am not sure where Aquamar Apartments are, but all Taxis are registered and meter. l use Taxis a lot between Los Americas to and from Los Cristianos and it cost me about €5 to€6. Sorry l cant give you more information but would say the drivers are always polite and helpfull and they don't over charge, if they do and are reported they lose there.. licence.
Taxis vary. Once you understand the price don’t pay anything more. Some of them do try to add a Euro or two and some don’t give you correct change. Let them know at the end if they try to charge too much and they then lower it.
Some are fine, some try to take advantage.
