We spent 5 nights in Josef's flat and we would come back anytime. The flat is exactly as described and looks exactly like the photos. Very large and flooded with light. The bathroom is very clean, the kitchen fully equipped and in very good condition.
The location is perfect, right in the old town of Prague. There are many cafés, bars and restaurants in the area. Public transport is within walking distance and ideal for exploring the city. We were able to park our car safely in the courtyard for an extra fee (very fair price).
Thanks for all the helpful tips and see you soon!
