Beautiful flat. I wish I could have spent more time there. I did not get to meet Lenka while I was there, but I was only there for one night. Very accommodating: I made the inquiry less than 14 hours before checking in, and Lenka made sure I would be taken care of at check in. (This was after a last minute change in travel date). Well kept and clean.
The flat is approximately a one minute walk to Charles Bridge and maybe 15 to the Old Town Square. Also, under 10 minutes to the stairs that lead you up to the palace and cathedral...after that is up to how long it takes you to get up those stairs.
