Hi bro!
Bucharest, an ugly city? First time that I’ve heard this, it’s pretty beautiful though. The thing is that people have different tastes, so some people may find it ugly and some may find it beautiful. But Bucharest is called the “Little Paris” for a reason.
Personally, I’m gonna move to Bucharest later this year and it would be nice to met DBL brothers IRL there.
Anyway, about Bucharest, if you want to visit, go in Centrul Vechi (The Old Town), it’s pretty beautiful, you have French type architecture there. The north is pretty beautiful too. Just make sure to not go in the south of the city, there’s nothing to see and you may come back without your wallet.
Especially neighborhoods like Ferentari, Rahova, Berceni…
About the rest of the country, Transilvania is a very beautiful region too, especially if you like old stuff like medieval castles, etc… There you have the Bran Castle, that Vlad The Impaler lived in.
If you like nature, you have the Dunarea, a very beautiful & known river in Romania. It’s located in the south-east of the country.
P.S: When you go there, just make sure to not take the Taxi but Uber, some Romanian cabbies will try to rip you off, especially if they see that you’re a stranger and don’t know the prices.
