After visiting the museum, I really have good knowledge about Azerbaijani literature. All thanks to the fact that the ticket already includes a guided tour (I think it's not useful to visit without an excursion). My guide was Aygun, some incredible girl with a lot of knowledge about Azerbaijan and her literature. I highly recommend it, it is an amazing investment of money (only 7 manats) and your time. There are guided tours in 5 languages (Russian, English, Azerbaijani, Arabic and Farsi).
An interesting museum. A visit costs 7 manats and a guide is provided. The guide tells a lot of interesting things. The exposition is on 3 floors. Sculptures of famous poets, manuscripts, many paintings by artists of the XX century - portraits of poets and scenes from life, household items. It is informative to visit, especially if you are interested in it. You can't take pictures.
