Overall it was a good experience to stay at Helen's. The place is literally 1 minute away from the beach. It's calm, spacious and well organized with a fully equipped kitchen. We also enjoyed plugging the speakers in both rooms.
On the down side, the apartment is a bit dusty and the kitchen could be slightly cleaner. There is no place to hang your clothes and the blinds are not light proof. The bed is very soft which and not appropriate for everyone's back.
Helen allowed us to stay late on our day of departure, which was very convenient.
