How hard is to find a WG(shared flat) in the Frankfurt area?

Hi all, Soon I am going to live in Frankfurt and I am searching for shared apartment. The first days I arrive I will stay at AirBNB and diring that time I will b looking for WG.

Consider your personal experiences how many time takes to find a wg?

How many requests have you made ?

I am not going to spent a lot of money so which do you think are the most reasonable prices neighbors near citys?

Many thanks in advance

The minimum termination period for rental contracts in Germany is three months. Most places are advertised (and the better ones quickly taken) shortly after that. So you should be prepared to sign a rental contract several weeks to three months before you can move in. Anything below one months is unrealistic.
A roon in a WG will cost about €300-500/month (incl. utilities, which are often paid separately from the rent). More for furnished places (which are rare).

The most likely way to find a WG is at Universities or other school for higher education. Usually there are pinboard where people advertising looking for flatmates.
