Very bad experience from the start to the end! I was there with my two children. I booked all inclusive trip with Solfaktor travel agency for the first week of January 2019! We arrived at the hotel at 8:30 pm in the evening. The staff forgot to bed the couch in our room used for the third person and there was no extra blanket that I could use during the night, and they gave us a room where the heating system was not working, it was very cold during the night.
The next day early in the morning I asked to change the room. But in the evening the same day I and my older son we both got diarrhea! Luckily I had medicine with me which we took straight away so we were fine until the next day. But their two pools was not heated so the kids couldn't swim during the whole holliday.
The children spent the whole time playing table tennis and billiards.
The day before we returned home the tabletennisball disappeared! I personally contacted 4 people who are responsible for the kids club and asked them if we could get a new ball for the children to play with it again. They promised me that soon we will get one and nothing happend.
On Wednesday morning, one day before we were going home, when I woke up, I discovered marks on my arm and foot, which I recognized directly, lice bite. Because I got the same marks when I got back from Hurghada trip and I finded the insect and killed it. When I went to the doctor then to show him my marks he ask me if I just returned from a trip abroad because these creturs dont live in cold weather.
I went straight to the receptionist Mr. Farid who worked then to tell about what happined, but he claimed that the responsible person for health issues is not available in the morning and he will comes back at 19 o'clock. Okay I say I'll return laiter. I called after we had eaten dinner from our room and asked the front desk but no one could talk to me at 20:30. Therefore I decided to go to the reception personally at 21:30 and then I met a person who was responsible for health reporting, at first he denied the problem but when he listened and saw the marks on my arm and foot, he asked me what I wanted to do? Do you want to change the room? I said I have already been bitten by these small animals and I will leave the hotel at 12 o'clock, the only thing you could do is change all the bed clothes and all the duvets and they did.
