Our long weekend in Berlin was perfect, Sebastian gave us all the information we needed before our arrival. Plus he is really easy to get along with, we stayed for 4 days and just lived our life without any constraints :)
The apartment is big, pretty clean and very well located, next to the Ostreuz station from which we can go everywhere in Berlin quite easily. The Friedrichshain neighborhood was the perfect choice for us !
Thanks again Sebastian :)
