A wonderful collection of paintings. When visiting Vienna, I recommend going to the museum and just wander inside and admire the works of art. It is better not to limit the visit to one day. A few visits add a pleasant aftertaste. About ticket prices - it's not cheap, but it's worth it. Moreover, there are different options.
A wonderful collection of old masters. Interesting exhibitions are regularly held. There is an audio guide in Russian. The museum is large, it takes at least three hours to view the entire exposition. I highly recommend this place to visit. If you come to Vienna, then this is one of the first places to visit.
A very rich art collection. The largest collection of Brueghel's paintings. The famous "Venus in Furs" by Titian (it was from impressions of her that Sacher Masoch wrote his novel). "Peltskin" by Rubens, Veermeer and of course the famous Salera by Benvenutto Cellini
