We negotiated a custom tour with Irina, driving for four hours to view Art Nouveau architecture followed by a two hour tour of the Yusupoff Palace, concentrated on Art Nouveau interior design. She took us to very interesting sites such as the central railway station and the Tolstoy apartment block that we would never have seen on our own. The Yusupoff Palace was absolutely spectacular. So, a nicely chosen tour, plus Irina has encyclopedic knowledge of related history. Altogether a first rate day.
