The place is perfectly located: close to the train station, national museum, old center of town as well as the more modern districts of Vinohrady. Everything was sparkling (!) clean. The bed is big, the kitchen has everything you'd need for a home-cooked meal and the flat is located in a gorgeous building.
To us it appeared a tad bigger on the photos than it was in reality but we didn't mind since the flat comfortably hosts two people and offers everything one needs.
Check in was very smooth and so was our communication with Ondrej.
All in all - everything was perfect :)
