Next to the Ukrainian embassy is another diplomatic representation, the Azerbaijani embassy, located in building No. 16, which is a significant urban-forming object.

This building did not come together all at once, but gradually: its left part existed as a two-story stone house of Major A.I. Chelishchev as early as 1806, while the right part was built in 1874 by the widow of a professor at Moscow University, I.I. Davydova. In 1905, both parts were combined and reconstructed for the furnished rooms 'Little Paris', resulting in a three-story house with decor that has been preserved to this day.

M.V. Nashchokina, a well-known specialist in the history of architecture from the late 19th to early 20th century, describes the house as 'a very peculiar building in the Art Nouveau style due to its decor.' Abundant stucco livens up its strict forms: thistles, snake-like hair of female masks, male masks under the cornice, surrounded by fruits and leaves of grapes, look discontentedly at passersby. The metal grilles of the three balconies on the third floor are also made in the style of decorative Art Nouveau.

In the older left part of the house, near the passage to the courtyard, there was once the Writers' Shop, the door of which was later turned into a narrow window. The shop appeared in 1918 as a book trading enterprise in shares, which was planned to be transformed into a cooperative publishing house. Here, books were sold by writers M.A. Osorgin, B.K. Zaitsev, and V.F. Khodasevich. Ariadna Efron recalled that at the Shop one could purchase not only printed works but also manuscripts: autographs of writers and poets, handmade books made from various types of paper, sometimes illustrated and bound by the authors. During its existence, the Shop sold about two hundred such publications, including several books by Marina Tsvetaeva, neatly filled with red ink.

In 1921, the Shop moved from the premises of the former library it occupied in building No. 16 to Bolshaya Nikitskaya, to building No. 24, and the vacated premises were taken over by the Comintern dormitory.
