This is such a great place to stay in Berlin - plenty of space, super clean and everything you need for a really base for your Berlin visit. The area is great, with plenty of local bars and restaurants, and it's really well connected - 12 mins walk from Sudkreuz station, with excellent connections to the rest of Berlin and beyond, and only a 35 minute journey from Berlin Brandenburg Aiport.
Gerhard is super helpful and provided lots of great local advice and he met us locally on arrival to take us to the apartment personally. He also recommended a little Italian place in Kreuzberg which served possibly the best pasta I've eaten in years!!
Great place all round :-)
