Carlotta's house is located in a location, which you have access to a the most important places around Catania. If you are for holidays, this is the best house for you, but if you are going to Catania for work (and you need your laptop), you might find it inconvinient because there is no WI FI and there is a poor connection to your mobile phone. If I come to Catania for holidays this time, I would stay in Carlotta. Another tip I would like to give to Carlotta, is to think about changing the way of entrance, because for me I didn't felt safe to have only access by using a code, visible from anyone passing through the street.
