I'll be happy to put you up in a cozy room in my apartment. There is a comfortable sofa-bed, a beanbag chair, a table in case you need to do some business and some nice decorations. The apartment itself has modern furniture, a split bathroom and a kitchen with all things needed.
The apartment is located in a beautiful area not far from the National Library of Belarus. There are a lot of trees and a water channel nearby. It takes just 10-15 minutes by public transport to get to the city centre.
