Claudia’s apartment is really lovely - very simple and stylish in an excellent location with lots of bars and restaurants nearby. The nightlife is great in Friedrichshain.
The apartment is great for a short stay but you might struggle for a longer stay as there is no washing machine/microwave/toaster etc. It was perfect for us though!
One thing to note would be that although it says that the check in is flexible, Claudia asks for a €20 fee if you check in late. Other than that, everything was perfect! Would definitely stay here again.
