I did think about not posting this as it sounds like you are looking forward to the trip and my experience wasn’t so good so might dampen your enthusiasm. Hopefully yoshimi will post about the good stuff to balance.
It seems like somewhere with a lot of poverty and problems- go with your eyes open
I’ve been here a few times:
ball room dancing restauarant
bit touristy but interesting
Have to say though that Bucharest was one of my least favourite places to travel and I didn’t get a good impression of the place.
Last time instead of heathrow (which was fine) I flew from Luton to Bucharest’s 2nd airport on a low cost airline rather than BA because the flights were at more convenient times
the airport was not much more than a shed
there was a family having a full on argument in the middle of the arrivals hall – the chap spat in the womans (wife?, mother?) face and raised his hand and back slapped her. no one around seemed to care. dog running around barking.
people pushing in front of each other to get to passport security and just generally treating each other with minimum civility and respect
the female colleague I was travelling with was very nervous and a bit taken aback
coming back the other way, the queue at passport control to enter UK is quite an eye opener also
good to experience different places though and made me realise just how lucky most of us in UK are
