Hi Simon, welcome to My Bulgaria!
We have so much information on our forums that we ask everyone, new and old members alike, to familiarise themselves with the search facilities as often what one is asking is already answered elsewhere! You can find a guide to using them here:

It takes a little practice to get the most out of them but half the battle is using the right search terms (keywords). For instance, car hire
and car rental
will bring up many discussions but you will find one by looking through the results pages that is full of recommendations. Likewise try building materials
. You may want to play with adding your area name etc for more local information.
Good luck with your new cottage and with using this site!
