Sebastians place is exactly like the pictures, big room and I liked that there was a lot of space to hang up my clothes. Besides that it had an awesome big bathroom. S-bahn is just a few minutes walk away and there is a supermarket literally around the corner. The communication was perfect! Sebastian is a really friendly host, he checked in halfway to see how I was doing. His roommate Anne was there during my stay, which was nice to be able to ask some things and have a little chat. For those who enjoy cocktails, there is a bar (Omega) at the end of the street. You can sit outside, enthousiastic crew and great drinks. Can really recommend a stay at Sebastian and in Neukölln :)
