This museum is just four rooms, with many photographs, letters and portraits from the life of Tolstoy. Don't expect a furnished house or something alike, the place has also a large room used for conference, so it's more like a permanent exhibition in an elegant conference center.
Limited paneling in English, many descriptions in Russian. I would recommend 20 minutes...
Khamovniki could be considered a city of its own – here it’s possible to find some of Moscow’s most important cultural institutions such as the Pushkin State Museum of Fine Arts, the Novodevichy Convent and Trubetskikh Estate, great sport locations such as Luzhniki stadium and aqua complex, and long and beautiful Luzhniki embankment. Pick your preferred form of transport to explore the area – bicycle or river cruise during the summer and taxi in winter as many of the great places are situated beyond a short walk.
