Sadly we didn't get to meet Cindy as our timings meant we missed each other, however she was very friendly and thoughtful, she was very helpful to get us settled when we arrived (albeit by via phone/text)
The apartment is very nice and cosy, with everything you need. It's conveniently located near U-bahn and S-bahn stations, shops and restaurants in the area; and next to Tempelhofer feld which is lovely. You can rent a bike in a nearby shop and stroll around. Berlin is an amazing city and this was a great place to stay!
