I’ve been out to Romania to work (many weeks at the film studios in Snagov) and we were utterly spoiled by staying in the Marriott in Bucharest, but we travelled throughout the country on location and it’s probably one of my favourite places on Earth.
Definitely explore the Carpathians and Transylvania, it’s so beautiful. Bucharest itself has a few not so nice areas (keep your cash & cards close) but I’d probably put it on a par with some parts of London.
I was out there throughout the winter, so I can’t comment on weather (November/December/January in Bucharest is bloody freezing, but Transylvania is spectacular in the snow. Friends that have worked there since say summer can be very hot & humid. And midge-y!
The people are very welcoming & friendly and there’s lots of choice of cuisines in the city. Even in the Marriott there were multiple restaurants & bars (if the Lebanese restaurant is still in the shopping concourse at the hotel, it’s epic).
Bucharest did have a huge problem with stray dogs - almost all hotels had their own dog packs, as did the studios - and unfortunately we did see many strays who had been victims of the heavy traffic.
Of course, like any place, be alert & cautious at night in the city, however I wouldn’t say it was more frightening than many spots in London or New York. And yes, like a PP above, some parts are a dump. But then, there’s shite places in every city I’ve visited around the world.
It’s a decade since my last trip there, so the dog issue may be very different now of course.
Have a fabulous time!
