The main bedroom smelt very strongly of mould. We coughed a lot the first (and only) night we slept there. We then moved the mattress to another room so we could sleep more safely (although we could still smell the mould a bit there.
We had to wash all the cuttlery and plates when we arrived, as many of them were not properly clean. And in general the house was not clean (windows, dust, mould and other nasty things in the dish drying rack) and things like the taps, the curtains, the doors were shabby, difficult to use.
We would never stay in that location again, and will be less likely to use FeWo-direkt again as a result of this experience.
