I have to agree with some of the earlier reviews that first impressions when arriving to the street address is a giant "What on earth have I booked?" However, once you drive through the entranceway, climb the stair to the entrance door and step inside, you realize you have discovered a true hidden gem!
We were given an extremely pleasant welcome and shown around a wonderfully decorated, and very clean old palace with high ceilings and modern conveniences. Our room was spacious and comfortable, with clean, crisp linens, cold A/C, and a well appointed bathroom.
Acquadellarte B&B is extremely well positioned for walking to many of Catania's points of interest, and dining options, and for an extremely easy trip to the airport.
I too would suggest reserving a parking space in advance as the street options look very busy.
I certainly recommend Acquadellarte B&B for an affordable stay in Catania.
