Jan & Sarah's place was great and exactly as described. It took me less than 15 mins to walk from the train station. The apt is centrally located and around lots of good restaurants in Prague. Jan also provided me with guides that were extremely helpful, including a foodie guide specifying locations around the apt and around other Prague areas which was helpful to plan my itinerary.
The apt looks exactly as in the photo. Very cozy & comfortable. As a solo traveler I felt safe and secured in this area, and wouldn't doubt to go back to it. Public transport was less than a block away if you don't want to walk, even though you can everywhere.
