I like this library, designed by Finnish architect Alvar Aalto (hence the name). It might not look very special on the outside, but the inside is amazing! The enviroment inside is very calming and they have a huge variety of books, sadly though, I do not speak Russian, so I could not read these. They have free WiFi, however you need a Russian phone number to sign in to the network. Great library for studying, working, and reading!
