We booked a one week stay for the first week in January. Everywhere was really clean and tidy and no need to tidy up when we arrived.
It was warm and cosy and we really enjoyed the sunny terrace for the afternoon relaxation. Although we had a couple of cold days the flat was warm enough using the AC units for heating. The owner offered to supply carpets but we really didn't need them.
I would recommend a stay here at any time of the year
