Erman was very communicative. All messages were responded by him in timely manner. On the first day of our stay, the bathroom and toilet was clogged and Erman quickly sent a plumber and the issue was resolved immediately. We love how industrial and hip his place looked. His place was enough for the 6 of us. There's a huge screen tv with netflix and fast wifi to make us feel like home. Tram was just opposite the place which was very convenient for us. Overall, we are fully satisfied with our stay in Berlin. Kudos to Erman for being a super host to us. Well done.
