Fully decorated German apartments to rent

I have just returned from a family trip to Frankfurt's Christmas Market, where we spent much time marvelling at tat from a different culture. I was very taken however with the fantastic painted bird boxes on offer at one stall. I now feel we have done the poor old Grey Wagtails and House Sparrows a dis-service with our 1960-esque concrete carbuncles. I wonder if we may find tiny burned out cars lining the Troll Trail before long, and the better off birds emigrating to Germany where they can buy a stylish pad for a few Euros.
