Got a great deal walking in without a reservation for 5 nights. 70 Euros for a double. Everything I needed plus. Everyone mentions walking down to the National Museum (Wenceslas Square) but you can also walk in the other direction (uphill) to the I. P. Pavlova metro and tram stop. Here you can catch the 22 or 23 trams which go to Lesser town, Prague Castle, and the monastery. Get a day pass for metro and trams - some of the tourist areas are a climb uphill.
Nice room, quiet, great Czech beer in the lobby bar, friendly staff, ordinary European breakfast buffet with lots of choices in a nice "sun"room, free high-speed dialup internet, sauna, hot hot water, wonderful lobby.
