Communication with our host was really easy and fast. We arrived late in the night and that was also no problem. The apartment is nice for staying a few days in Prague. Some things in the apartment did not work, e.g. ventilation in the bathroom or some of the lighting in the bedroom, so that was a minor annoyance. The location is perfect, it's a good starting point for walking to the center, but there's also a tram station right there. Overall it was a nice stay, we especially loved the balcony.
