I've just finished doing the same for Edinburgh, UK and share many of the OP's frustrations. The monopoly that many letting agencies have in that they are also managing apartments adds to the shortage of accommodation in Europe's largest cities. Unlike in previous years, besides a worsening of the availability of accommodation I have also noticed an increase in scammers this year (i.e. people copying pictures from other city's agencies and trying to convince people to pay pre-deposits or application/administrative fees to 'secure keys').
