I have loved staying at Jan's place. We were a group of 7 friends and it was just perfect. We felt very confortable in the house and the lovely garden was great for hanging out. The room are spacious, the house it's very well decorated, super clean and has everything we needed. We have been in Berlin for a partying weekend and it was great coming back in the morning without worrying to wake up someone else. Jan and his family live in the same garden plot but the houses are separated so you feel the confort of being on your own. At the same time was handy because when I could not make the kitchen hobs working (I am not familiar with induction hobs) I could ask for his help easily and he was really nice and friendly about it. We have been using cabs during the night to go out spending between 10 and 15 euro (depending on where) but during the day we have been using trams to get into town and it was very easy and well connected. I recommend without shadows of a doubt to stay at Jan's.
