We're planning a budget honeymoon very last minute which is looking like it will be a short break (4-5 nights) in Berlin. I suspect the cheapest option is going to be a self-catering studio/1 bed flat through Air BnB (though I'm open to suggestions for any other source of cheapish non-hostel accommodation).
I was wondering if the Mumsnet hive mind could offer any advice on which areas would be a good base for general touristy activity and if there's anywhere we should avoid?
We're happy to do a lot of walking but somewhere with good public transport options would be ideal, and while we're not particularly fearful people we'd also quite like to avoid being mugged.
Also, any suggestions of things to see and places to eat which we won't see in a guidebook?
