Pyatnitskaya 12, the main drag of Zamoskvorechye. Although called “museum” this place is more of a low-key cultural center. Painting and drawings, usually from the Tolstoy era, are regularly exhibited there, and small semi-private music events. It is one of many small hubs of “cultural” activity scattered around but not usually mentioned in guide books. Go to the Tolstoy Museum page and scroll down for photos of what’s inside. Steps from my apartment that you can rent at a very reasonable rate.
