Stayed here in February 2023. Big appartment with four beds in two rooms. The furnishings are quite basic, but the appartment was very clean. The location is great, close to Unter den Linden and the Brandenburg Gate. The apartment is an easy walk from the U2 and U6 U-Bahn lines.
The letting agency that runs the property was helpful in setting up late check in, but you do need to arrange this in advance. Katarina sent us a list of recommendations for restuarants nearby which was very nice of her.
