Your best bet actually comes from the main taize.fr site, where they mention St Sylvester's church in Bucharest, when talking about Brother Alois' visit to Romania in 2008:
Fr. Bordasiu, current parish priest of St. Silvester, who began sending groups to TaizΓ© from Bucharest in 1990, remembered the visits of Brother GrΓ©goire already in the 1970s.
So certainly, if anyone can help you with taize prayer or finding a community of those who associate with the order, St Sylvester seems like the place to start.
