Dear Armand, thanks a lot for your feedback.
We're glad to hear that you and your partner enjoyed your stay in our cottage and liked the town of Hildesheim.
As to your inconveniences, please consider that the cottage is part of our own home and we use it regularly for our own needs, so it is not the same as a hotel room. The kids' toys - Lego castle and arena - were put altogether in one corner of the sleeping floor. As you fixed the booking only one day before your arrival, I'm sorry there wasn't enough time for me to remove it, neither before your arrival nor during your stay.
As to the garden, it's our family's space and not part of the airbnb offer, as you can read in the advert. We have five kids so it's normal that you find some balls and a bobby car in the garden. However, our guests are free will behind the cottage and will always be welcome to enjoy our BBQ and sun loungers.
I was glad I could give you some information about the restaurants in our town and also to help you out with our hairdryer. As we just have this one, I'm sorry I had to ask you to give it back each morning.
For the future I'd recommend you to either take your own dryer with you or - even better for your demands - take a hotel room (4-5 stars) with late check in option (as you arrived really late).
With best wishes from Hildesheim,
