Very great to stay 4 nights at Wera's place. It is closed to Brandenburg Gate, starting point of marathon (2km). And it is very easy to find supermarket and restaurant because there are just a few steps of walking.
Thank you for room design and cleanliness. It was made me sleep well before running in the world major marathon.
If somebody wanna go to Berlin for marathon or for soemthing else, strongly recommend for Wera's place and you will have a great moment and great nihht.
