Me and my wife have been in Catania between nov. 27th and dec.1st. We have chosen Santo's studio and, believe me, it was the best decision we have made this trip. The host is a great person, we arrived in the morning and although the (normal) check-in is at 3.00 PM he made everything in his power to check as in in the morning (and of course he succeeded). He was very kind to offer us a short lesson about Catania and what could be seen there and made himself available for us on whatsapp during the whole stay. The apartment is small, but charming, equipped with... everything and the view towards old town center from the rather large balcony was breathtaking. It also has a "strategic" position in the city: maximum 10 minutes walking distance to any interest-point (Center, Railway Station, via Etnea etc.)
It was one of the best places we've stayed in our trips around Europe (and there were 6 trips this year only). I have no hesitation to recommend this place to anyone visiting Catania. Grazie, Santo!
