We deeply apologize for the stress and inconvenience you had during your stay.
It is for the first time that a flea issue is reported and the time wasn't enough to fix the problem 100% during your stay. We do have regular proffesional pest controls and provide each room with repellent tablets as well. But fleas can come again any time, since they can feast on humans as well. So in your case it is also possible that you got the fleas from anywhere during the first three days and then carrying them in the apartment and vice versa. As I said before, I am really sorry about the situation and it might be the case that because of the yard and strays in the area, fleas did infestated the appartment dispite the sprays and tablets we use almost everyday. I just wanted to be clear that because that was the one and only time we had any flea issue reported, that there is a 60% possibility that you got the fleas from anywhere on the island: forest, seashore, etc. and we can't be 100% sure that the fleas where in the appartment before you arrived. As you stated yourself the first insident was after three days. In anycase we are going to take all necessary steps and means to avoid such issues in the future. We are thankful for your time and honesty and we hope that you will have some positive memories as well from your Rhodes trip.
