Me and my husband stayed 1 night in this hotel and I must say that our experience was quite bad. This is definitely not a 4 star hotel. I have no idea, how on earth they managed to keep the 4 stars for so many years... For example, in the EU, there is a Hotelstars Union, which is the official European hotel classification entity which sets standards and ensures correct industry standards, so both the customers and the industry participants are committed and the inspections are carried out to ensure the right qualities.
The hotel room:
The room is outdated and the bed was hard, the wall papers were old and some were missing. The floors were worn and the toilet was old and awful. There was a lot of noise from the other rooms and despite the warnings with the help of the reception, they didn't stop and kept on making loud noises until 3 in the morning.
I can only advice one thing: do not waste your money and stay here. There are many other real "4" star hotels in Antalya. Please do your research on your hotel choices and do not end up in a situation as we did.
