I made a request before to have a connect room since I have small childern and that was one month before my arrival, but I was disappointenet that they ask for extra charge which was almost price of one room for same period time, that only to open doors betwwen the two rooms.

The location of the hotel was good, allowing the fast transportation to the city center (only 2 stops) and sightseeing areas. To get to the conference center was quite easy (S8), then U-Bahn, but on the weekend the frequency of S-Bahn was quite pure and we must wait about 28 min to get it . On the week days was much better and faster. The rooms are modern and useful designed, clean, very small bathroom, but quite dark (2 floor). These is because, the bilding is not very high (5 floors) and constracted with inner yards with opposite walls. This was the main problem, although I ask very much for a lighty room in upper floor and motivated it by extremely importance for me , as I am working for years in the hospital, in rooms without natural light (only artificial light). And although I stayed there for the a quite long time (1week including meeting and vacation) and ask them every morning for change, it was not possible to get suitable room for me. Something like this, it was never happend to me in any Hilton Hotel before, as I am very often staying in Hilton for meetings. Also since years I am a member of Hilton Honours. This was a big mas. Restaurant employing is very young , nice but unexperienced people , so it was not always very perfect. All together would be much nicer, if the reception would be willing to get more respect and anderstanding againsts client requests. I will qualified this Hotel as max. 4* hotel, but newer 5*.
