As soon as we had booked to stay at Robert & Katka's apartment they were very helpful and always quick to respond to any queries that we had. Straight away they helped with transfers from the airport and were more than happy to help when we advised we would be checking in late because of our flights. The apartment is very modern and tidy and is located in an ideal location. The walk to the Charles Bridge/Old Town only takes 20 minutes but it is a beautiful walk besides the river. I would advise anyone that is thinking of staying in Prague to stay here.
