Talking about Germany, short-term rental in hotels or holiday apartments and long-term rental of an apartment are different market segments, with different regulations in some areas.
- Most landlords will do some financial background checks of their tenant. You might come up empty on the most common check, which makes you appear as a "high-risk" tenant.
- People are required to register with the municipal authorities in their place of residence. A hotel takes care of this for the guest, a landlord does not.
- Tenants have to enter an individual contract with a power company, with readings of the meter when they move in or leave.
So even if there is no law against it, it might be impractical for just a few months. Subletting might be more practical.
