I spent the Easter weekend at Sasà’s place. The house description is pretty accurate, the place is actually very cozy! The location is relatively close to good clubs, rail stations and the East side gallery. If you don't mind a 10/15 mins walk, you can also easily get to the nice bars and cafes in Friedrichshain. The apartment was clean and well kept, perfect!
Sasà is a great host, clear communication and very polite. I recommend him and his apartment 100%!
