We stayed there with 4 colleagues for a week and had a good time. It is ideally located, easy to reach, only 5min walking to the conference center. You have to climb stairs (no lift). The AC in each room is ideal! Some rooms are noisier some others but overall all are very calm. The appartment was very clean. Ideally there would have been some more kitchen soaps and towel to our disposal, but I am sure this will get fixed in the future. The bedrooms are very big with a lot of closets. We did not cook but the kitchen seemed quite well equipped. Overall I would recommend renting this place!
