We had a wonderful stay in Margherita's place. A couple of things I would note are - it's listed as having WiFi, but you can only pick it up in one corner of the flat (no WiFi or phone signal anywhere else, as it's a cave), it is very patchy, and is not strong enough to be picked up by a laptop (phone only). Also, if you are over 6'2" you will not be able to stand up straight, the ceilings are very low! Apart from that though, the place is lovely, very well located (and you'll be super fit going up the hills!) and Margherita was great, met us at the flat with water, was very helpful in recommending various places and was responsive when we had a query later. Loved Naples too, would recommend this place :)
