Our friend has a hotel in Ravada hotelirisbg.com
It is brand spanking new only completed last year.
They are situated close to Bourgas airport about 15 Mins by car and will arrange pick up and return on request at a small cost of course. Ravada is near the very popular Sunny Beach resort and very close to Neesebar heritage site.
The web page will be updated shortly, and there will be special rates for long stayers.
We stayed there before it opened to the guests and it really is very good.
Also try Natures Best near VT. Jane & Bill are super host. The accomodation is super.
