Cornelius's apartment was a perfect place to stay for 3 of us making a short visit to Berlin. The location was ideal, with the immediate neighbourhood fun for a wander, a nice bar or getting a few things from the shop. The flat was extremely well setup, including a very good kitchen. It was nice and warm, but still bright and airy. We were there in January but I can imagine it also being lovely in summer with the balcony and sunshades on the windows.
Lots of thoughtful and helpful facilities, like tourist guidebooks and maps, and a curtain to screen off the sofa bed area if that is being used. It was spotlessly clean, very comfortable and I loved the plants everywhere. Somehow it felt like a little temporary home while we explored the city... We would like to visit Berlin again and would stay there again without hesitation.
We arrived later than hoped, but communication was always quick and without hassle, we were also able to check out a little later in the day which was very helpful so we did not have to carry luggage with us all day before our flight home. The lift was also really helpful for us with luggage and cranky knees!
Thanks again, we really could not have improved on this stay in any way.
