After reading other reviews I expected a way better condition of the apartment. The reality is that it needs better maintenance: walls are covered with stains and scratches, window in the bedroom covered with rust, hall lights are blinking, sofa is dirty. When we checked in, floor, some dishes, toaster and kettle were dirty. After our complaints hosts came to wash dishes and change the kettle and the toaster, but we ultimately had to clean the rest of apartment by ourselves. Saying about humidity, it's around 80% in December.
Also there are pros - excellent location, restaurants and metro are one minute walk, silent street, hosts are easy to communicate. But despite this we were disappointed.
