Location - right on the beach and in centre of Old Town by the beach. Location couldn't be better.
Private steps and foot-wash that lead direct to beach.
Stunning, uninterrupted sea view of entire beach.
These are minor points, easily resolved:
Check-in, before leaving they want lots of online forms filled out and photo of passports uploading, couldn't get that working and don't have friends passports anyway.
You have to go to an office out of town to collect keys and pay, it was closed. Difficult for return airport transfer booking as they want to pick you up from where they dropped you off.
No information in apartment - we didn't know there was private stairway to beach for first few days.
No wifi, and no information telling you that, we spent ages trying to connect.
Only Spanish TV stations.
I know you have to buy your own stuff, but they could leave what previous guests leave behind - there was no toilet rolls, bin bags, washing powder, dishwasher tablets, washing up liquid, sugar, salt, pepper, ice cube tray, corkscrew, shopping bags, beach towels, so straight to shop.
Aircon would be nice in 3rd bedroom and front room.
But none of that really matters when you see the view.
