The most important thing to note about this place is, as other reviewers have mentioned, it is not just one apartment like Airbnb! It is a complex with many different apartments, so although the style is the same, the apartment you are designated will most likely not look exactly like the one in the pictures! However, we really enjoyed our stay at Nena Apartments. The building was very cool architecturally and felt very safe, the apartment we were given was spotless (albeit missing a lightbulb, so a little bit dark!) and had good amenities. It was also close to multiple U-Bahn and S-Bahn stations, so that was great for getting to the areas further than walking distance. Although we didn’t end up doing so, we also really appreciated that we were able to leave our luggage with the staff if we needed to. Overall a great stay and we would return again if in Berlin.
