Wow - This Marriott is the epitome of great service. Everyone I encountered went out of their way to ensure my needs were met, including the bellman who everyday remembered me and made sure I had transportation to go where I needed (I was here on business travel). This hotel's location was also good -- just a few minutes walk to nearly all of Prague's tourist attractions (5 minutes to Old Town; 35-40 minutes to Prague Castle only because it's mostly uphill the way there), including numerous restaurants and bars. My room was very spacious and quiet. The Executive/Concierge Lounge was also well appointed and clean._ Will definitely stay here again if I'm in Prague.
