We stayed at Alex and Kate's appartment from 17/12 until 23/12,
The appartment was just like the photos and was 4 min away from the tram station and 15 min total from the center.
Also, it was very clean, quiet and warm.
The hosts were very nice to us and very helpfull.
One of the pros is that the appartment is at zizkov area,where all the good pubs are,so you don't have to take the tram or any other public transport to visit one, beacause most of them are in a walking distance.
I totally recommend it!!!
