Regarding key collection from the office, that is not unusual with accommodation agencies such as Gestaltur, which rent out privately owned apartments in residential complexes, perhaps without a manned reception area where payments can be accepted or keys issued. With clients arriving throughout the day at complexes all over Benidorm, it perhaps wouldn't be feasible either to meet each one at their accommodation. Gestaltur has been operating in Benidorm for a number of years, you may find more on them via Search.

With regard to the Santa Margarita Apts, we have one very old topic HERE. Just bear in mind if reading any feedback about individual apartments that there may be a number of private owners or agencies renting property at this complex, and so standards and facilities may vary accordingly.
