Ilona was a friendly host. Her apartment is located in Mitte directly at the metro station Heinrich-Heine-Straße (U8) from where you can reach the most exciting places within seconds. Her apartment is very clean and spacious - it fits 4 people without doubt. It is located on the top floor so you have a nice view. Ilona responded quickly to my request and was happy to arrange the key exchange whenever it suited us best. If you want to spend some time in Berlin (Mitte) I can recommend her!
