Nice hotel...but...listing on Hotels.com (and elsewhere) is slightly misleading. They claim to have a restaurant and bar. They have neither. Granted there is a small disclaimer that food and beverage services may be affected by Covid-19 restrictions. However, they also claim to have a bar and a restaurant serving international cuisine. We expected that there may be limited seating or restricted hours or even a limited menu, but arrived to discover the bar was a vending machine in the lobby with limited drinks and snacks and there was absolutely NO restaurant serving food (although breakfast is still available in the mornings). That said, it would not deter us from staying there again as there are several restaurants within easy walking distance and the English Pub is almost right next door. The rooms were clean, tidy and pleasant and staff were all very cheerful and helpful. Just a let down when we had expected bar and restaurant services to be available on-site.
One other thing, and this is not a uniquely Ramada Flensburg thing, is that there are no ventilation controls in the room, like AC or heat. Apparently this is Germany-wide "thing". No hotels in Germany have in-room HVAC controls, so if it's a warm evening and you want some cool air. you need to have the window open and put up with the street noise.
