Very easy to communicate with Nic, he always responded to our questions very quickly and helped us out accordingly. Brilliant location in Berlin- great access to all of the sites let alone close to lots of restaurants/ bars etc. Only negatives were no curtains or blinds on the Windows which we weren't warned about and the bed was more like a fold out couch and therefore quite firm to lie on. Those points aside, we had a great stay in Nic's apartment and would stay there again if we were in Berlin due to the brilliant location
