We enjoyed 2 days at this apartments. Unfortunately, we didn't meet Costa, but Maria welcomed us and was very hospitable.
About apartments: everything was clean, they provided set of bath towels, there is a sea starting immediately at back yard, we swam at morning and evening.
Kitchen at neighbor hotel is good (we had a breakfast there)
For those who travel by car: apartments don't have dedicated parking, but we were able to found parking place around.
Overall, we did like our stay.
