I booked this hotel because it is close to the convention center. Being there on business, internet is important. This hotel have the worst internet solution I have ever experienced in a hotel, and on top of that they charge 15 euro a week for it. Both mine and my colleagues iphones where constantly thrown out of the network after around 10 min, and to get in again we needed to put in a long user name, and a long password. I stayed at room 416, a junior suite. the room have had serious water damage to the floor, and all wood ends in the parquet was bending upwards. The air conditioning was not working very good, but that was due to bad maintained units. I cleaned the units, and then they worked very good. The beds in the room are very hard, and it looks like they have bought double beds without buying the upper mattress. The rooms have no alarm clock, no tea/coffee, and no iron. This is the only 4 star hotel I have ever stayed in that have lacked this. There were also a lot of positive things at the hotel. First of all that the staff so what they can to help, and they were always polite. The distance to the city center is not very long, and there are trams and buses going very often. if you prefer a taxi, it is only 7-8 euros to the town center. The hotel staff have direct booking of taxis, and it never took more then 5 min until a taxi showed up. If you can live with a bad internet connection, this is a hotel to consider if you go to a conference.
