Gerhard was a great host, he kept waiting for me at home 1 hour more in his holiday just because my flight got delayed and he stayed in touch with me since i did my first booking advising me what kind of cloth to bring to the great landmarks to visit ..... The flat was very clean and warm and it has all the amenities which it let you feel home so i was washing my cloth on daily basis and yes i have OCD :) - the flat is at the ground floor facing the streets from a side and a garden from the other side but you cannot hear any single noise . just close the shutters make it black out and sleep deeply. the area where the flat is located is not the best and Gerhard made it clear from the beginning but it has all the public transportation around from the bus station in front of the building the the u bahn 500 meters away to the Sbahn 600 meters away. i do recommend Gerhard place and i would love to re-rent his place once i decide to visit Berlin Again- Thank you Gerhard
