Two of us stayed for 4 nights in this apartment. Check in was seamless as clear instructions were given prior to our arrival. Location wise, I would say the apartment is very convenient because it is about a 5 minutes walk to the U-Bahn station(Mehringdamm). But if you prefer to walk, the apartment is about a 30 minutes walk to the attractions such as Topographie des Terrors and Checkpoint Charlie, to name a few. There are a lot of food options along the way. Neighbourhood is safe and lively. The apartment is well equipped with hot water / microwave / coffee maker / toaster and stove etc. Had some issues with the toilet but it was resolved almost immediately. Didn’t see any neighbours during our stay but it didn’t matter as we were out and about exploring Berlin for the most part of our stay.
