Arrived at hotel around 11pm after a long day travelling and nobody was at reception. Knocked on a few doors around reception and still no-one. Waited a significant period of time before the receptionist came out of the office I knocked on and literally did not care he kept us waiting. It was then the longest check-in ever, he even asked me at the end of the check-in process to email over my booking which I found strange as never have I done this in my life. Went to our room and it smelt very dusky, to the point I couldn’t stop coughing so I went back down to reception and was told he couldn’t do anything about it. I asked if the hotel was fully booked he said no. So I asked why he couldn’t change my room then? He then said I had to pay €10 to change it but I was being downgraded a room type? Why would I pay €10 to downgrade a room type. He was the most rudest man I’ve ever met. I asked him for his name and who the manager was, he said Nils and he was the manager. We finally sorted our room at 2am! The next day I found out he wasn’t the manager, he was just the receptionist over night. On the other hand, checking out we met Lara, she was absolutely brilliant! 5* and so so welcoming. She helped and talked through the loyalty scheme and helped us with our route to the airport. Absolutely amazing- thank you! She is a credit, unlike Nils. Hotel: good location for transport everywhere. Approx 12-15 mins train to Alexanderplatz. A lot of construction at the minute but ask during check in (as long as Nils doesn’t check you in, you’ll be fine). Rooms: on the new side which is a walk, rooms are fab very spacious but modern. Shower gel, shampoo and conditioner in bathrooms. Breakfast: very good, chose your ingredients for your own omelette! You can make your own waffles! Bar called Van Gough connected to hotel, looked ok but didn’t visit. 3* review only due to Nils on reception being rude and unwelcoming!
