Bucharest is well worth a visit, some great late 19thC grandeur, excellent (cheap) metro, and the "entertainment" district was extensively refurbed 10 years ago (info here: http://ar-tour.com/guides/bucharest-guide/lipscani.aspx).
On the downside Covid is rampant currently in Romania with sky high infection rates and a death rate at around TEN times (per million of population) the UK rate.
