We stayed at Natalia for four nights with my wife and our one year old baby. This was our third time in Prague and the flat was the best we have experienced. The location is amazing, it is four station away from a P+R parking lot where we didn't have to pay.
The downtown is 10 minutes by tram or underground. Also this was one of our quietest staying in a big city. There was absolutely no noise during the night!
The flat was warm, heating is really good. The kitchen is better equipped than a usual airbnb flat. Bed is very comfortable and warm.
Since we were with a child we used the crib and the feeding chair Natalia provided, which was a huges help the we didn't have to transport these in the car.
I can only recommend it for everyone!
