The house is perfectly located to see whole Ortigia and feel it's atmosphere. Sarah is great host, communication with her was easy and she was always ready to help us. Although the house is really beautiful and the location is great, we needed some time to get used to artificial lighting all the time - but it is how it is with historic buildings with small windows directed to the narrow side streets. The neighbourhood in general is quiet and peaceful, occasionally some loud tourists or annoying motorcyclist can move near your windows what was really perceptible in the house but it isn't anything that Sarah, the host, can improve :) All in all we were really, really happy about our stay in NAVI HOUSE, Sarah did everything you could ask and even more to accommodate us. Small downsides that I pointed out (lighting, audible noises from outside) are related to the localization and ancient character of the house and wouldn't be as important to me and my wife, but were a little bit noticeable because of our 2 years old daughter :)
Totally can recommend this place and in the future we would be willing come back!
