The hotel is comparable to a IBIS kind of hotel. Nothing special, in the middle of nowhere and ok-ish if you are just for a couple of hours to sleep. No 4 star at all.
The lady at the reception was not kind and not service minded. We had to call 4 times in 2 hours for a amenity we requested. When they still did not arrive after 2 hours, we put the do not disturb sign on and went to sleep. One hour later they knocked on our door while we were sleeping to bring the amenity!! So 3 hrs later.
Also be aware that the hotel airport bus only carries about 10 people as there is no extra space for the lugguage, all other seats has luggage on them. So even at 5 am, there were so many people waiting for the next bus for half an hour later, that we would have waited for 1 hour to get the next bus from the hotel. There is only a bus every half hour.
So as you need to take a taxi anyway, I would recommend to get a nice hotel in a nice area in stead of this hotel.
