Definitely Recommended! We had a great time at Alex's place in Pankow. The place amazing. The room was spacious and light, and the neighbourhood was great. Even though it is a little bit out of center, we were not bothered by it at all, since the public transport (S, U, and M) was just outside the door. Moreover, Alex was a truly amazing host, with his warm welcome en heartfelt hospitality, we felt really at home in Berlin.
And, If you love cats, you're in for a treat.
