These are nice pictures, a very nice space it seems. Much more appreciated when you live in a city, from what I know about Berlin, it seems to be very busy. Here in Bogota, being a capital city, there is a lot of traffic, smoke, violence, and what corresponds - unfortunately - to the big cities, but an hour away there are very nice natural spaces that are worth visiting to forget the city, at least for a while.
I know - I was in La Vega round about two years for living and working. The smaller city has about one hour distance to your capital. Not so far... But another world ;-))
