Was a great stay! Ferdinand was not there but he left us clear instructions on where to find everything etc. even drew a hand written map for us. instead we met Valentin, his room mate he was extremely friendly and gave us advice on locations to eat and visit. The place was just 2 blocks from a subway station u bahn so getting around was very convenient. Berlin has an amazing transportation system. Place was clean and as advertised. Well worth the price. Would recommend!
