We stayed one night at Villa Mullerbeck, 2 adults and 2 kids (9 years old). We actually were looking for a place for 2 nights, but the whole reservation process was a bit clumsy and at the end, they were apologizing to tell us they will have only one night for us so they will give us the suit in a regular room price of 59 euro + the cost of 1 extra bed 20 euro. OK...
The place itself looks new and the location is very peaceful and nice; they have a beautiful garden nearby a small lake and a cute mini golf and everything seems to be clean and tidy.
The room we got on the ground floor is not a suite by any reference.. It may be a bigger than the standard hotel room and had a nice terrace with a lake view, but it was the lack of any fancy or specialty, on the contrary, I would say, it was basic. The "double" bed was actually twin beds that got attached and when I looked for a laundry bag in the cupboard (a regular thing even in basic places) they didn't have one. Same for the bathroom - it was clean, but no extras. Not even soap by the sink.
The 2 weakest points for me were: 1. The breakfast - very Esnonian style with no international sense. 2. Every time you we run the water in the bathroom sink there was a very bad smell coming from the floor hole/ drain; practically every time I washed my hands or brush my teeth, the smell was so bad to the level of feeling like throwing out. The unbelievable thing was, that later, during check out time, I let the lady know about this problem in the room. Her answer was: "Yes, we know about it and we cannot do anything about it"....
So: it's a kind of new and refreshing place among other options in this area, but hard to consider it a very good place. I would come back, it a room on the second level would be available and would set the expectations to the level of "nice but nothing to write home about"
