I’m searching from Rotterdam for an apartment around Lyon and deciding whether ImmobilienScout24 is reliable enough to remain my main shortlisting tool. Coverage has been useful, and I particularly value the rental-yield information. However, duplicate listings, unclear freshness, stale status and inconsistent floor-area figures make comparisons difficult. The next step after contacting an advertiser is not always obvious either. Has anyone found the mobile filters and saved-search alerts dependable, especially once an advertiser has been contacted?
