The location of the apartment is absolutely perfect! It is really well connected to public transportation and on walking distance from major attractions and points of interest. Also, Yaz is an absolutely perfect host, always there if you need help, very friendly and giving good advice. I was here with my family (5 people in total) in August and we had a great time.
The apartment is very convenient for a family or a small group of people. You have everything you need and in perfect order to make your stay in Berlin more than comfortable.
I would definitely come back to stay here in my next visit and I absolutely recommend it!
