We love Paul & Jana's place. It is really nicely done out and had everything we needed for a stay in Berlin. The location is great to explore Berlin on bike, foot or public transport (really close links). Paul & Jana were brilliant communicators leading up to our trip and kept in touch whilst there to check all OK. Really recommend this place and hope to return.
Best tip: Walk to Templehof Airfield which is 5 mins past Sudstern station. Best in afternoon/eve where it has a life of its own!
