The premium room was not worth 225€/night (without fees and taxes). Upon arrival the room was too cold (17°C), when I wanted to turn on heating the air conditioning was not working. There was a strange not-locked door inside the room connecting it to another room; the space behind it was covered only by a thin wall/possibly the door from the other room as well. The room was too noisy from all sides, I was not able to work from there. Additionally, there was quite a lot of dust on some surfaces and the furniture was worn out which didn't justify the price for a 4-star hotel. The water tap in the bathroom was sticking and squeaking so loudly that anyone outside could hear it whenever I tried to turn on the water. Also it took a while for the hot water to start flowing. I requested a room change but the hotel was fully booked during my stay.
I stayed only for 2 nights but cannot imagine staying longer, definitely not a good value for the money.
However, the breakfast was good. The location is close to the airport and NATO HQ, but there is nothing to do within walking distance. There are also no dining options around except for the hotel restaurant.
