Jiri and Kate's place is great. My wife and I stayed there for 4 nights. The apartment was clean and had all the amenities listed. The area is awesome as you get to interact with locals and get great Czech meals at a great price. There are also plenty of mini markets to purchase food within walking distance if you would like to cook. My wife and I bought snacks and breakfast essentials that helped us save money. About a 5 minute walk there's a small plaza where there's free WiFi and a local cafe that sells beer for about 33 korunas about $1.50. the apartment is also a 10 minute walk to the subway and tram station which allows you to take it 3 stops to old Town, the castle, and pretty much anywhere else in Prague.
