This is a spacious and bright apartment with a territorial view from most of its rooms. It actually seems larger in person than it appears in the photos. In addition, there was an entire extra bed beyond what we were expecting, i.e., there are two beds in each of the two good sized bedrooms, plus a double bed in a very large master bedroom. Being in die Mitte, it is very central to most of the main tourist and memorial sites in Berlin (Brandenburger Tor, Reichstag, Memorial to the Murdered Jews of Europe, Unter den Linden) and it is only a couple blocks from two U-Bahn stations that can take you into any of this incredible city's diverse neighborhoods. There are also nearby grocery stores and the Mall of Berlin if you need provisions of any kind. This is a perfect base for exploring Berlin's main attractions for short-term stays.
For longer term stays, there are a few things that should be noted: the wifi is very basic and if you plan on digital nomading from here, it is sometimes a struggle (even with the upgraded router), particularly if more than one person are sharing the limited bandwidth. Appliances are basic, but clean and functional. The floors could use a sanding and finishing in the dining area. Overall, the neighborhood and building are pretty quiet at night. Finally, if your stay is longer, note that the refrigerator is quite small, which for a larger group of people will mean almost daily trips to the market/bakery, but this should not affect those who are staying short-term or eating out.
