Loved the place, they just completed renovation and offer three-level historical interior as an interactive guided tour, a few rooms furnished in 19th century style ( as of the last house owner merchant Sapozhnikov), another floor decorated in 17th century old-Russian way (as of the first house owner Ershov) and a cellar with husehold things and a hit at its former fortifications and underground passage to the river Klyazma, excellent concept of a fortified rich man`s house of that time, staff is friendly , they also have a small olden-time furnished tavern that offers tea and other traditional drinks ... I guess in the newest guidebooks they call this House of Ershov & Sapozhnikov, as they rearranged the town`s historical museum into several new formats now, and this heritage house is surely worth visiting (they only have around 20 buildings like this in Russia)
