Olivier was very easy to communicate with before the rental started and answered all of my questions. Picking up the key was easy and the apartment was easy to settle in. The neighborhood is really perfect -- lots of great little shops and cafés and also a large grocery store around the corner. It's super convenient to Nollendorfplatz, where there are four U-Bahn lines, Eisenackerstraße, where there's an additional line, and several bus stops, all within 10 minutes walk. There are also a lot of restaurants of all types and price categories. The apartment itself is warm and well furnished and lit. It also has an amazing shower. I had a chance to meet Olivier and his partner during my stay and they were super friendly and accommodating regarding a small issue that I had in the apartment (which was caused by me). I will be staying there again next month and would recommend it without reservation.
