You cannot find a better option for this size, location and price. Sara made checkin very easy and was available to us when we needed help throughout the trip. The place is certainly not modern though. The showers would suddenly become freezing and then incredibly hot and there was sometimes no water pressure in the sinks/showers (although maybe this is just a general problem in Palermo). The place is very old and if people are moving around/talking on the second floor it is very loud on the first floor.
But, of course, you get what you paid for. The place is certainly reasonably priced for the quality and the pictures and accurate.
