Excellent location just few minutes of walk to Vaclavske Namesti, metro station and Narodni Muzeum. Flat is really good - we've been there with 2 small kids for a week without any problems, underground garage and elevator are also an advantage. And most important - even if this is a city centre location there is so quiet outside, so you can keep windows open (no air conditioning) and you won't hear any city noise at all. I can recommend this location for the any short and mid-term stay in Prague.
