We arrived on a Tuesday and were informed that they had no concierge until Thursday. We asked the manager to book us a walking tour. The next day he informed us that there was no walking tour until Saturday. We later found out that there were several tours daily. The carpet in our room and hallways was stained and tiles everywhere were dirty. The regular desk staff, bartenders and housekeeping were pleasant. The manager had little interest in helping us until the concierge arrived on Thursday, besides telling us, except to tell us where the tour buses were located. When the concierge arrived on Thursday, he immediately booked us a walking tour, got us admission to the Reichstag and helped us get too many locations by public transit. He recommended restaurants and jazz clubs. His name was Johannes Bannert and his help was paramount in enjoying our stay in Berlin. When I asked about the swimming pool, I was informed that it had been closed at the start of Covid and never reopened. In all other Hotles we stayed in the pools were opened even in Munich. So this was not a German policy just laziness on their part. The workout room was nice. The hotel did not live up to our accommodations in other 4 star locations in Budapest, Prague or Munich. We had trouble getting our room cool enough with the air conditioning. When the maintenance man came up he said it was fixed and that we were in Germany not the United States. Again in the other three cities room temperature was not an issue
