Me and my girlfriend stayed for a week and had a great stay! Clean, Spacious & save that is how we would describe it. The hosts are friendly and always up for help if you need it.
The area is save and walking distance from the main square. Besides it being save and the good location, it can be a little bit noisy due to people sitting on their balcony at night.
Over all we would rate our stay 5/5 and would come back if we would visit Prague again!
