Thanks for the TR and the pics! Bucharest & Transylvania have both been on my list for a while. Looks like I should make a little more effort to get there!
Question to the OP - you mentioned you hired a private driver on day 2. Can you please share some more details on this? Did you use the concierge at the IC to do the hiring or did you find the driver yourself? Did he charge you extra so he could drive home at night?
