To be able to display you the information of the apartments, we have to visit the website first our self. Like you know opening a page takes some time and and varies a lot between different website. This plus the time it takes us to find the information on the page, creating a screenshot, saving everything and then sending it to you can take a while. Depending on how many people are currently requesting pages there is maybe an additional delay because we have sadly not unlimited resources. However normally it should not take longer then 5-10 seconds.
We are always working on speeding up the process but are still in a very early stage so please bear with us. Thanks!
