In our opinion this apartment is fine for a short stay but not suitable for a long winter stay.
The lack of curtains and rugs anywhere meant, despite the wall-mounted heater in the lounge, it was often cold in the apartment, especially as there were no shutters over the patio doors, which would have at least made the place warmer in the evenings. The doors didn't lock properly and so there was a security issue, although the apartment is on the second floor (no lift). The north facing bedroom was very cold and had no form of heating. The wardrobe space was very limited due to storage of items already in there. The bathroom was fairly new and in good condition.
Victor the owner was very helpful during the booking procedure and at our request provided UK TV for our two month stay in January and February. The south-facing balcony was very sunny and the position of the apartment was perfect with no need for a car; 2 mins walk to seafront, 5 mins from the supermarket and 15 mins from the town centre. Overall the price was very reasonable. We enjoyed our stay in Santa Pola but wouldn't book this apartment again for the winter.
