10000% recommend everyone to rent Alex's Airbnb! His flat is spacious with tall ceilings. The bedrooms have lots of storage space and the beds are very comfortable. His living room has two large sofas that can easily seat 6 people with additional armchairs. There is also a nice little patio for those who enjoy having a coffee (or beer) outdoors.
The location of the apartment is impeccable. It is close to an area that is bustling with activities, famous breakfast joints, cafés, cool bars, and a flea market, which are all within a 5-minute walking radius from the flat. It is also conveniently located next to a subway train station that leads you directly into the city center in about 20 minutes.
Alex is an extremely attentive host! He took the additional effort to provide us guidance to navigate the train system and made sure we had everything we needed on the first day. He is very knowledgeable about the history of Berlin and shared with us countless local gems in the city!
