As a single traveller the apartment is great. It has everything you could need, in a beautiful building and good location. I'm sure it would be good for a travelling couple too. Nearly everything is within walking distance, plus there is a cycle hire shop about a 5 minute walk away. So there is no excuse not to explore Berlin!
If there is only one thing you do in Berlin it has to be to visit the Reichstag Dome at sunset, it's absolutely unbelievable!
Thanks again for being great hosts. Everything was easy and communication was spot on.
