We stayed at Eric and Gini's lovely apartment for a week during the end of Oct 2016.
Our hosts were lovely people and we also got to meet their awesome dog, Ruby. It was also Halloween weekend during our stay and our hosts invited us to a costume party they were throwing - turned out to be one of the unexpectedly fun highlights of our Berlin trip ;)
The apartment was clean, beautifully furnished and everything required for a comfortable stay was provided. It was also so easy that they lived next door and were always available if there were any problems.
The apartment was also close proximity to the S+U Bahn and trams, so it was well connected and easy to get around the city. There is also an Aldi and bottle shop around the corner, so it's real easy to get groceries if needed.
We would highly recommend this apartment to anyone thinking of staying in Berlin, thanks guys :)
