All information regarding the minimum rental period of each listed property can be found in the expose. For most flats this is teo months. Owners prefer tenants who wish to rent for longer periods of time (up to one year or even longer). This is why it is worth letting us know if you might want to extend your contract or not. Very few owners offer their flats for just one month.
There are often many applicants for one apartment. Even if you want to rent for the minimum amount of time, the owner will, more often than not, decide to let the flat out to the person who will rent it the longest (1 year maximum). If you apply months in advance, it may well be the case that the owner wants to wait a little while to see if they can find someone to rent it for a longer period. Do you let us know exactly what you are looking for, when you send us your request for an apartment. Let us know what you need, which districts, maximum rental price, number of tenants, desire to view or extend the contract etc. and we can provide you with suitable options.
