The flat is gorgeous, clean and modern inside. We were 4 in the flat, so 2 of us slept in the sofa bed. The sofa bed was already prepared by the time we arrived. Was so comfortable! Even for a sofa bed. The flat was really clean and the people in the reception so kind and helpful. The location is the best. You can arrive walking to the downtown, with lots of amenities around the flat.
Josef was always kind and helpful. He sent us a guide with great recommendations for food, tourist points and supermarkets.
I would definitely recommend the place and I would stay here every time I back to Prague!
