Well folks, your search is over! After staying at Demien's residence for two nights I am 100% certain this is the best Airbnb in Prague and will be the place of choice for our future stays :) The location can't really get much better as the flat is about 45 seconds away from the Old Square (without the masses of tourists tho). Demien is the most responsive and welcoming host ever, he agreed for us to check in early and leave our bags in a secure place after our check out. The flat itself is HUGE and has an amazing palacial, spacious feel to it. Amenities are all in perfect condition and the flat is very clean with all the mod cons. It's great for a couple for a romantic weekend away, as well as a group of friends. An absolute 10/10!
