Mark's appartment is very well situated. You can walk to all the main attractions of Prague and it's not far from the central station as well. Just down the appartment there's a bakery and a small market open all night. Mark's place looks exactly like the pictures. It's very big and it was clean. Zuzana, Mark's colleague, was very friendly and gave us a lot of tips on places to visit. The only down side is the bathroom. The shower isn't really easy to use because of the restricted space and the water didn't evacuate properly from the bath. But overall, we had a very good experience.
