First off, Martin and Jan are very easy going and it was easy to keep in contact with them. Their place is right near the metro, where it is two stops away from the central station, and very easy to catch the 22 tram to all of the tourist destinations. If you're feeling ambitious, you can walk to all of these locations as well from their place, with the exception of Pražky hrad. They both had great suggestions for what to see and what to avoid, and they were even kind enough to join me for a few pints. It was truly a pleasure staying with them, and I would gladly stay with them again.
