I found it impossible to find a rental in Germany. I tried for three months in Frankfurt. No luck. Tried for three months in Dresden and Gorlitz, still no luck.
In Frankfurt there was very little inventory of apt's for rent. What was available was overpriced and not so nice. I'm not talking about the center of Frankfurt. I'm also iincluding ALL the surrounding areas too. No supply at all.
In Dresden and Gorlitz I found a lot of apt's but most of them were still under some kind of construction or renovation. It was extremely rare to find an apt. that was well put together and available. You just don't find that. Most apt's available were not desirable at all for some reason.
Try looking for houses to rent and it's even worse. They don't rent houses in Dresden or Gorlitz area. You have to go to the suburbs to find that and even then nothing is available. If a house was available it was a complete disaster.
