I tagged a few days vacation on to a business trip and moved from a 289Eu/night business hotel to a 30Eu/night small hotel. There was obviously a change in standard but I was pleased with what I received for my 30EU. My room was on the ground floor and had a double bed, private bathroom. Everything was beautifully clean. Bed was firm which I like. Plenty of hot water anytime of day for the shower and great water pressure. Two radiators in my room and I only needed them on very low, but again I could get the very hot if needed. No A/C (hey it's 30Eu!) so maybe an issue in the summer, but it was October and I was very comfortable. Plenty of food at breakfast but typical German style (cold meats, cheese, fresh rolls, eggs, yoghurt etc. Coffee was OK, I like it stronger normally. One member of staff spoke no English, another was fluent. I would suggest you should know enough German to book yourself in and understand when breakfast is served. And to say thank you!
Wifi was fast and reliable, I could stream TV programs without issue. Area was fine. I left a nice new hire car parked outside with no problems and felt perfectly safe walking around at 11.00pm in the dark.
Would I stay here again? Yes. I'm trying to work out if the 250Eu/night extra my business hotel cost was really justified as I was no less comfortable here.
