We stayed for one weekend at Bogdan's place and had a really good time. The room is big and neat, the apartment fully equipped, and situated in a very nice neighbourhood besides the touristic sights, but not far from the center. Bogdan and his girlfriend are very kind and open-minded. Staying at their place is relaxed - if you need help, they'll be there to assist you. And if you are interested in getting to know Czech lifestyle (including Prague nightlife) they are a very good address.
