I LOVED PRAGUE, It was perfect trip for us. Jarda's house is Great. very clean, fast internet connection, hot water and other things just perfect. and its really central. (praha 2). I haven't seen sightseeing bus in Prague, because they dont need one. there is Tram everywhere. you can see the city with tram. you can get in tram 22 from of the house. its like 10 mt far away. and tram 22 goes to Charls bridge.
Jarda is very helpful for everything. Thank you
