Hotel Columbus in Frankfurt am Main

1. The staff was rude. I arrived earlier than check in time and wanted to ask if I may leave my luggage there. The receptionist spoke really rude and asked if I know reading my check in time (before even hearing me out, as I didn‘t even think to ask for the check in). In the end, he said it was ok for me to leave it there, but the „luggage room“ was really tiny, already full and my luggage big enough. Then he asked me to put in the cleaning supply room after he took the cleaning cart out. By the time I arrived later my luggage was already taken out from there and put in the breakfast area.
2. The surrounding area is really shady and worse than imaginable. Full of drug addicts, drunk and homeless people.
3. The security of the hotel, especially in such conditions (described above) was very poor. Each morning and evening was a different person at the reception. I stayed for 4 nights and never seen a person twice. Almost daily the entry card got deactivated and I had to request to the front desk to reactivate it. They never asked for a document to check if I request activation for my room, only asked for the room number, even though they have never seen me before. By this I mean anyone staying at that hotel could have entered in any room.
4. There is no noiseproof. My room was on the groundfloor and I could hear anything happening on the reception, the cleaning staff who spoke on the hallway, them vacuming the floors, other people talking.
5. It wasn‘t clean. In the bathroom upon arrival there were at least 4-5 hairs in the shower and on the bathroom walls. Discusting to be honest.
6. I used my „do not disturb“ sign 3 days (1 day until 11 and the second day until 1 pm). On the third day when I left the room and wanted to take the sign from outside, the sign was gone. Not sure if any other guests have taken it (don‘t see the point) or the cleaning staff (probably bothered they had to „clean“ the room after 12 pm (If what they did could be called „cleaning“).

I’ve never seen so many junkies in my life. I later learned that the location is one of the most dangerous in all of Germany. The stay itself was mostly fine, although the “flat screen TV” was tiny and a cleaner left our door wide open for the whole day. Total disaster.
