We had a group of 4 (one couple, one single and a one year old) stay at Carls house.
The house is really spacious and beautifully renovated in a country style, the heating works very well and the house is super close to the shops (an easy walk to some small miscellaneous shops and a couple of cafes).
Self Check in was very easy and we were greeted with a welcome pack of chocolates, chips and biscuits. If you do plan on cooking my suggestion would be to bring everything, there were no staple items except salt, pepper and oil, do not expect condiments or anything like that. Coffee machine is good but BYO milk.
There is no dining table in the house so we ate at the kitchen bench or in front of the TV but this may be annoying for a larger group and unfortunately the fire place was not working during our stay (Carl gave us a partial refund for this inconvenience).
The portacot is not that big so perhaps BYO if you have a good travel one, the high chair that was provided was perfect.
All in all we enjoyed our stay at Carls house.
