We came over in early may last year and stayed in an apartment at Palm Beach, just off the seafront near Seril 1. Arrived at 3am, all quiet and dark obviously. Woke up and decided to go for a swim, looked out of the patio doors and the pool was empty !!
We stayed for 12 days and the pool was only just filled by the last day, sat on the balcony for nearly 2 weeks watching the maintenance man re-grout the tiles in it.
We went up to Letoon hotel most afternoons for a dip, bought a beer and checked my email using their Wifi.
It was quite quiet, they only had 2 rooms occupied, maybe if it was busier the offer might not have been there.
I usually find a subtle hint once asked where you are staying opens the door to say " it's nice but we have no pool " and an offer for use of theirs usually arrives ;o)
