Heidi was amazingly helpful and a very warm and welcoming host! She went out of her way to make sure we were comfortable and had everything we need. The house is beautiful in a very quiet area a bit outside Berlin. Even though the house is not located in the city itself, it was still very easy to travel to the centre, there are very frequent buses that go straight to the centre of Berlin without any problem. The room was spick and span clean and very cosy and we had access to our own private bathroom. I would definitely recommend staying at Heidi's house to anyone looking for a quiet and welcoming place to stay in the Berlin area.
