Thor's place was awesome. Central to a couple of transit lines and easily walkable to many restaurants.
Thor was a really wonderful and charming host. He was very kind and offered me many recommendations of things to do as well as making me coffee in the mornings and offering anything in the fridge. On my last morning he insisted on preparing a tasty english breakfast before my flight home.
In addition, Thor has back ups of anything you might run out of or have forgotten (toothbrushes, shampoo etc.) To top it all off, his two cats are friendly and welcome you into the home immediately as family. They will keep you company if you leave your bedroom door open and invite them in :)
I would absolutely rebook with Thor on my next trip to Berlin.
