Natalia's place looks just like in the photos; it's a studio split into 2 areas, suitable for a couple or a family with 2 children.
It's close to the city center and easy to be reached from the Airport as well (direct metro line).
What one should take into account when booking the apartment during winter is the fact that it's extremely cold (I would assume 15-17 degrees inside) and maybe not that adequate for the kids. It has 2 ACs, but honestly they don't heat that much.
What I would suggest to Natalia would be to heaten up the apartment prior to arrival in case there are kids among the guests.
I would definitely book the apartment again during summer!
