We (2x couples) rented Bert's place for a long weekend and found it to be the perfect base to explore Berlin. The spec of the apartment with 2x bathrooms and 2x double bedrooms (1 with pull out sofa bed) is great for a group of 4. The area of Berlin the apartment is in (Prenzlauer Berg) is full of cool bars, coffee shops and restaurants. The city centre is about 25mins away (e.g. to Brandenberg Gate) by public transport and there are S-Bahn, U-Bahn and Tram stops within walking distance. Thanks for hosting us Bert!
