We had a good stay here. The space technically can only sleep 4 comfortably, and there is very little space to move around in the apartment.
The heat and lack of cross ventilation warrants atleast a fan to enhance circulation. While fans are not common in Germany, majority of the guests are out of country, will be a nice added touch if this is provided
Dunja was super helpful and prompt in her responses. Also very helpful in getting us settled in
The gym next door and the house being on the ground level adds to noise and discomfort at night, if you look past this, should be ok.
