I stayed together with my son and we had a perfect stay. My husband also stayed with us for some days and the flat was big enough for all of us. It's a nice and bright apartment, it was clean upon our arrival and everything was fine throughout our stay.
Werner welcomed us very nicely and left some drinks for us as well.
The flat has a couple of nice playgrounds near by for children of all ages.
The only thing is that the internet is not very strong but good enough for checking emails and chatting.
All in all we would stay again in this flat.
