I can't rate our experience at Jan's place highly enough. I've used Airbnb dozens of times and I don't think I've ever had a host go so above and beyond in terms of providing local tips and care to ensure we had a great time. Jan met us the morning of our check in at the front door, and then took out a map to explain how to get to the Prague attractions and how to navigate the transit system. He was in touch a couple times throughout our stay to ensure we were comfortable. He was also very accommodating with an early check in and a late check out.
The space itself is clean, comfortable, stylish and well located. It's very spacious for a studio apartment, and the little garden with the friendly cats was a nice bonus! We were a stones through from the major tram routes that take you anywhere you want to be. Honestly, I could live there! Great spot.
