This is an amazing place to stay in Berlin, if you are okay with climbing 2-floor because room was on 3rd floor. The best part was kitchen and amenities, I specially liked the Sodastream machine! Cooking facility were like home. Hosts were really kind and nice people, a million thanks to Mr. Rudolf and his wife for setting up my room and providing me home-like accommodation. I didn't feel like I am away from home for a single minute! This place is very near, about 700m, to Subway station "Onkel Toms Hütte (Berlin U-Bahn)", so no need to bother about walking around to get public transport! Just walk to Onkel Toms Hütte (Berlin U-Bahn) and get U3 subway! There is "ALDI" supermarket also at the Onkel Toms Hütte (Berlin U-Bahn) station, a plus! Can buy almost everything you require at very reasonable price! some restaurants also, a Vietnamese restaurant too!
From Tegel International Airport (TXL), it takes around 40 minute to reach this location by taking bus X9/ 109 + U7 + U3, so connectivity to airport is very convenient and economical!
In short, you are willing to get nice, calm and wonderful accommodation just go to #8, Auerhahnbalz, 14169, Berlin Germany!
