Great stay at Carolin's house!
The location is perfect, especially if you want to discover the east side of Berlin. It's also really close from public transports.
The neighborhood (Friedrichshain pretty much) is pretty cool! You can easily eat and have a drink.
The flat was clean and has a nice balcony where you can chill out.
Carolin is very friendly, available if you have questions and accommodating.
We recommend without hesitation!
