Nathalie's place is a great base for a short or longer trip to Berlin. It was very clean and had a well-equipped kitchen so it's possible to prepare your own meals if you like. What I liked most is that it, as it's situated in a residential area, made me feel like I lived in Berlin instead of just visiting it. The neighborhood is lively and has everything you need with regards to shops, restaurants and public transport. Communication with Nathalie was easy, and the whole process from check-in to check-out went very smoothly.
I really recommend this place and hope to come back one day!
