Bert's apartment is beautiful and is a perfect place to stay with two couples. Within a 10 minute walking radius you have grocery stores, restaurants and bars. The area is a nice place to be staying in Berlin as it is clean and safe along with having really good restuarants in the area it makes it perfect. There are two bathrooms and the bedrooms are both located on the upper floor, each with a different view of Berlin. The only issue we faced while staying was the wifi, it only worked on our phones some of the time and was very slow when it did and it never worked on any of our tablets and laptops which, is a bit difficult when you are travelling through Europe and you need to do research. Besides that I would highly recommend to stay at Bert's apartment!
