Ellen's flat is perfectly located in Berlin, close to several metro and tram stations. It is also absolutely beautiful! We enjoyed spending time there, just relaxing in between visits. The terrace is a big plus and the kitchen is well equipped to cook anything.
The neighborhood is very nice with lots of shops, bars and restaurants. Quiet and lively at the same time.
Communication with Ellen was good and her neighbor managed both check in and check out.
I highly recommend staying at Ellen's.
