We (4 adults 2 adult children 4 children under 10) stayed at Villa Edera for a week in January.
House
The house is very beautiful with interesting architecture, large living areas, a lot of bedroom space. The pictures are accurate. The bathrooms were excellent, with ample hot water. It is clearly a family home and felt warm and inviting, works of art and interesting objects in all rooms. And gorgeous majolica tiles! The kitchen was well stocked with cooking utensils and basic foods, crockery, and so on. There was a large laundry, lots of linen and so on. The central heating was very effective and there was an open fire and lots of wood. The pool and garden would be lovely in summer.
Location
The house is located on the outskirts of Catania in a small town. You really need a car because walking to the town was not very easy (narrow rd, no footpath , fast cars. There might have been an alternative route though, you could ask Paul if this matters to you). It is a good spot for day trips, we easily got to Taormina, Ortygia, Ragusa, Piazza Armerina, Mt Etna. I say easily although driving in Sicily was challenging and we'd only just found our feet by the end of the trip, (we should have hired an automatic). All these places were great, we wished we had more time. The upside of winter travel is that we had these places almost to ourselves (in particular i imagine in peak season Armerina and Taormina would be very busy)
Admin matters
Paul was very easy to deal with and was there when we arrived to show us the house etc. we had one problem a with a fuse and he was on his way immediately (ended up we sorted out). He also recommended restaurants and day trips.
Overall I thought the villa was very good for a group of our size and if you want to stay in this area of Sicily, I recommend it.
