Jan is very friendly and helpful.
The apartment is in the courtyard of a big apartment building on a busy street. Because of its location in the courtyard there is no noise at all, it is quiet as described. It is a lovely studio apartment with a modern bathroom with shower. A washing machine is available. The kitchen is fully equipped. The living-/bedroom is cozy.
With a 20 minute walk you can reach the old town of Prague and explore the city.
