I had an amazing time stayed in Jon‘s apt. First of all, Jon and his lovely wife were super sweet to me. They waited for me for my super late check in, (11pm!!!) gave me warm welcome, also provided me lots of super useful info. They are such the great hosts!!
The flat is in the best location of Mitte. The sunway station is just across the street ( 10 secs walking distance maybe?) Near by, there are lots of nice restaurants, bars, supermakets, coffee shops, for ladies, local designer boutiques. But don‘t worry, it is very quiet in the flat. Also you can enjoy the super cute private terrace by yourself! The flat is spacious, full of character, bright, and clean. If I visit Berlin again, I will stay @ Jon‘s for sure. :)
