This Airbnb looks exactly as shown on the pictures, and it truly is only moments away from the Wencelas Square - you can get to most major tourist attractions in Prague in 15 minutes by foot, if that's something you value!
It was clean, enough space for two people and the kitchen comes equipped so that you could cook your own meals in there for a week or so easily. The shower is also very good!
The only slight note I would give is that it might not be the best place if you're a bad sleeper - the windows don't filter out much noise and if the neighbours in the flats across the yard choose to stay up until the early hours, you will hear them. Other than that this place is perfect!
