NH Berlin Alexanderplatz in Berlin

I understand that this is a chain hotel and should have expected service to reflect this. They don't need to be nice to patrons , so they aren't. We stayed here for here for three nights and thought as a chain it would be really nice. I was completely wrong. This hotel is a splurge to stay at- for me anyway- I thought you would have been treated a bit better. On arrival we weren't even greeted with a hello. There was absolutely no friendlies from any of the front of house staff whatsoever. Some didn't even look at you when they spoke to you. We weren't even told that the hotel had a sauna untilt the last day when we were talking to other guests. The bar staff also were just plain rude. They didn't want to be bothered or answer your questions. I wasn't prepared to spend €21 per person for breakfast so I can't speak to that, however I did get the fish for dinner for €24 it was a joke. No salad and quite tasteless.
It wasn't the nicest of environments either, just a nothing hotel, unmemorable and wish I had of spent my hard earned money somewhere else. I got an email for feedback regarding our stay and answered honestly and that someone could contact me , what I received what an automated response which is what I expect with this review.
