For those that don't like long reviews: Doreen is very nice and welcoming host who respects your privacy and expects you respect hers. The dog may be annoying if you don't know how to deal with it (like me). Location is great.

For the rest of you:
Doreen is a great host. She left us some refreshments in our room before arrival and that was a lovely gesture. Everything was exactly as described in the listing. The only thing that was a bit off was the dog, which has a really loud bark for such a small dog and uses it every time any of us opened the door of our room which was a little annoying but at least he never barked during the night so we all were able to get a good night's sleep. As for the location - it was perfect for us, Mercedes Benz Arena was within 30 minutes on foot, which was the place where the event we were there for held place. Public transportation was also very close, no more than 20 minutes on foot. There were also a number of bars and places to eat around the public transportation. A Lidl shop was extremely close for all our necessities. All in all our trip to Berlin was beautiful and we are waiting for an opportunity to come and visit again.
