Roman's place has a lot of it's own unique charm! Clean, quiet, all you need. Interesting neighborhood. Very quiet location and building. Excellent book and CD collection I rocked out to some R.E.M. when spending time in the flat. Prague is a really walkable city so I was able to get around easily and quickly all over town.
I found the Tram confusing and accidentally rode one for free because I didn't know how they work.
Also I would highly recommend the Airport Transfer Service to the airport from the flat. Reasonably priced and easy online booking.
Thanks Roman!
