The location is simply unbeatable! You'll be within a very short walking distance from major attractions (Astronomical Clock, Charles Bridge, Hemingway Bar, etc). We were only there for three days so it was convenient that everything was so close by. The apartment is spacious, clean, and close to public transit in case you want to venture outside of Old Town. Robert was a great source and provided maps of the city. He was also very quick to respond. Our stay was much better than expected and if I'm ever back, I'd definitely stay there again!
