We flew into Varna and the Villa was a 45 min drive away, we used http://www.bulgariacarrent.com/ as recommended by the owner and had no issues with the car\pick up etc.
As has been said by the previous reviews, for the money, this villa was fantastic. We have a 3 and 5 year old and the pool was just the right size, it also has quite a bit of grass to let them run on.
There are a few local shops which stock the essentials, but its only 10-12 mins to Kaufland in Dobrich where you can get everything you need. The locals in the village speak little english, but they are really friendly and helpful, its a nice quiet place that seems like youve gone back in time. It definately suits a family holiday, theres loads of donkeys and geese and other animals for the kids to see as you walk around the village streets, you can see the shepherd with his flock of sheep & goats every night as you sit outside on the hammock. One other thing is security, you dont exactly feel as if you need to lock the place up, but you do of course just in case. We screwed up the security system a few times, and these big fellas who looked like bouncers from a london nightclub turned up 5 mins later. No idea how they got there so fast, but it gave you a certain level of confidence in terms of safety.
We had a few others small things happen, but we just texted our contact Katya, and they were solved quick as a flash.
The one negative is that the villa is air conditioned on the bottom floor but only has fans upstairs, this led to our first week being slightly hot when going to bed\upstairs, but if you open the windows (but keep the flyscreens up) the air gets through and its not too bad.
For us, it was the first time to Bulgaria, and to be honest we didnt know what to expect. The roads arent the best in places, and dont think about looking about as you walk the pavements as youll more likely trip over a broken paving slab (esspecially in Dorbich square) but its cheap to eat and drink, the people are nice, the weather is great (32 in the shade when we went in August) and they have countdown clocks on their traffic lights...!!! I cant believe itll be long before people find out about Bulgaria and itll be the new spain, but currently it feels like largely undiscovered gem.
Highly recommended, one of our most relaxing holidays to date....!!!
