I cannot recommend this group of websites enough.
I have properties on these sites and the beauty of it is that you only have to submit your info in English on http://www.rentbyownerbg.com
and it is translated into Bulgarian for you and placed on http://www.bgvakancia.com
. Also, when I have an email response from an enquiry I am notified by a text. Admittedly, if the response is generated from bgvakancia it is in Bulgarian but I simply use Google translate - not perfect grammar but it is acceptable and gets your message across.
Also, making changes to the Bulgarian site can't be easier. A quick email to the guys at Rentbyownerbg and the updates/amendments/changes are done almost instantly. They then email you to let you know that they are making the changes and when they will be visible.
Good people doing a first class job.
A big thank you
to Velizar for all his help
