We stayed at Ramfis's/Dieter's place only for two days, and we enjoyed every moment spent in the apartment. Prior to arrival, we had an easy and very helpful communication with Dieter, suggesting best ways to get to the flat. The flat was very clean, everything was ready for us prior to our arrival (bedding, towels), and Dieter was very kind and took the time to share what to see in the city. Location was great, very easy to get around the city, tram stop right in front of the house. Kitchen equipped with all you need for a dinner 'at home'. Would def recommend and stay next time when in Berlin!
