As has been mentioned previously, I have an arrangement for the keys to be collected / dropped off at the reception of the Daina Hotel. I find this is a particularly satisfactory arrangement, as the reception is open 24 hours a day - therefore if your plane should be delayed and you don't arrive until say 4am, then there's no problem picking up the keys.... Not always the case if you're relying on someone's housekeeper!
Ouch Baron - that comment was a little biting! For the record, we do send out keys directly as often as we can but sometimes for various reasons it isn't always possible. As stated sometimes keys are not returned quickly enough or at all. With the best will in the World, it doesn't matter how many sets of keys are cut each year there never seems to be enough.
Also if it is a short notice booking it again isn't always possible to send keys in time. As for your comment re our housekeeper - We are blessed with someone who is extremely professional and goes way and beyond what would be considered a good service to us and our renters. We always speak with our renters prior to any arrival and we know the flight number and time of arrival. Should there be delays then on the few occasions that keys are to be collected locally, there is a plan of action. Our housekeeper has often gone out during the night to ensure renters are suited including times when renters have actually gone out and left keys inside the villa. A service which perhaps a reception desk at a hotel would not be pleased to offer!
