The apartment is great, even better than it looks: big, comfy beds, small details (Aircon, kitchen and bathroom amenities...), nice furniture, good water pressure and temperature...
BUT: the neighborhood is quite shady, it's true that is close to the center, but it's dirty, poorly illuminated, frequented by drug addicts, and doesn't feel safe. I hate to say it because Oleg and the apartment were super nice, however being honest you should be aware before coming. We were 2 young guys so we were 'fine' with it, but maybe a different people would feel uncomfortable here at night.
