My girlfriend and I stayed in Christina's place for a little short of a week and it was absolutely perfect for our time in Berlin! The room is very spacious and the art and decor throughout her apartment creates a very cozy vibe. The bathroom and kitchen were always clean and we felt very comfortable and welcome during our stay. Also, her apartment is in a great location in Neukolln, as we were close to all sorts of funky bars, restaurants and public transit for getting around the city. We had a great time exploring the area every night! On top of all of this, we had a lovely time hanging out with Christina and Chris (her boyfriend) throughout our stay with them. They had awesome recommendations for the city, were always there to help if we needed anything and were super fun to chat with over wine in the evenings :) When we come back to Berlin we will definitely be looking them up again!
