Martins apartment is in a great location about 20 minutes away from most of the sights in Berlin (The U-Bahn was about an 8 minute walk) and was easy to get to from Tegel airport using public transport. The apartment itself was spotlessly clean and very well appointed - I couldn't have chosen a better place for our party of 4 adults and 2 children for our long weekend away. The area seemed safe and relaxed with loads of eating out and drinking options very close by. Martin was very responsive to my messages and requests in the run up to our stay. All in all this was a fab choice and I would thoroughly recommend Martins place for your stay in Berlin.
