We had a brilliant 5 night stay at Tia's place. It's really spacious and has everything you need to feel right at home. The beds were amazingly comfy and having two bathrooms was a really good touch - especially as there were four of us! The location is great - it's right on the canal and a short walk from 3 stations to get to central Berlin, but there's so much in the Kreuzberg area that you don't really need to leave! Tia's recommendations were great, we loved the Italian restaurant called 'Casolare' just 2 minutes away - best pizzas we've ever had! We would definitely come back again.
