We spent a wonderful 10 days at Angelo and Cristina's house. The view from the balcony is just like the photo. The house had everything needed for a relaxing vacation.
We were able to find parking near the house and also in a large parking area off of Via Galatea which was not that far from the house (the upper part of the parking lot is for paid parking but the lower part is free).
There are railroad tracks nearby but we were never bothered by any trains. We only noticed the trains if we were sitting on the deck and one went by (all of the trains passed quickly and never disturbed us).
The walk to Santa Maria la Scala was quite challenging (at least on the way back to Acireale) but well worth the effort.
We highly recommend Angelo and Cristina's house. Acireale is a good location from which to visit the eastern part of Sicily.
