Carla was a very welcoming host. She met us at the apartment early in the morning the day we checked in to accommodate our travel arrangements. Additionally she made a whole list of recommendations of sights/restaurants/bars for Prague. The apartment was even nicer than the pictures. There was plenty of space. The apartment was also in a perfect location just one block from the Old Town Square. The main negative is that the apartment suffers from loud noise throughout the night (roughly 11:00PM to 3:00AM). If you are a light sleeper I would try to avoid such close proximately to main square. Overall very nice apartment and great stay in Prague!
