The room was cosy, spacious, extremely clean, and very comfortable for 2 people. The bath and toilet were also very spacious and clean, with hot water available at all times. The kitchen area was very well-stocked with more cutlery and cooking equipment than you'd need for a short stay. WiFi reception and speed were excellent.
Anatoliy is a very polite and helpful host. He sent me detailed directions to his place well in advance. He helped carry my luggage to my room when I moved in and spent a great deal of time showing me the public transit routes and places to visit in and around Prague. I cannot imagine leaving Prague without visiting some of his personal recommendations. He's also stocked the room with a few different guidebooks. And if there's anything else you might need help with, he's reachable on Whatsapp/Airbnb.
I stayed there for 3 nights during the Prague summer, and there were no problems at all. It was a wonderful first Airbnb experience for me.
