The only good estate agent is a dead estate agent. My personal recommendation is to infect estate agents with ebola and then release them, hopefully they will then take the disease back to their nests and infect other estate agents.
We're about to finish construction on a decent-standard apartment building near the centre of Warsaw (Stare Wlochy).
Email me if interested (Robin.Gray@Malik-Construccion.eu) and I'll let you know who to contact for a viewing.
