I've recently learned, hunting apartments in Spain, that many realtors don't want to deal with Russians. They find them too crude, and no amount of money they are willing to throw at them, seems to make up for the feeling of revulsion.

In some places, they simply mention to them that there's a thriving gay community in the city. That seems to be enough to make them go away...

I think it's brilliant, and I also think large concentration of immigrants in one place ends up destroying that community’s reputation and invites trouble.
