Toni & Alex's place is centrally located within Berlin so it's very easy to get to/from anywhere you'd likely want to see if visiting Berlin. Both hosts are very attentive to communicating as quickly as they can. I had issues opening the door (pulling rather than pushing...a "cultural" difference of door culture) but I was able to contact Alex who enlightened me to German door culture.
The place is tidy and simple but has everything you'd need. Thanks again for everything Toni and Alex!
