Thank you Dario and Roberto

We had a really nice stay at catania! the appartment is perfect for 3 or 4 persons, exspecially there is two sleeping room, two showers and a nice living room. We had some cold water in the fridge when we arrived:)
One room has two beds, which are unfortunately only 190m*0,8m accroding at least to my estimate (i didnot measure); so if you are really tall, it might be critical; but for me it was totaly allrigth. the other bedroom has a big bed..
Bathroom is totally clean and also kitchen.
AC is working very good, so not problem with hot summertime.
If you like it dark in the night, no problem: windows can be closed with kind of roller shutter (I cant remember the right word for that)

You are very central, perfect for going out in the evening :)
Although there is a street just next to the appartment, it is not really noisy, since windows are quite good.
Parking is a little difficult; but we used a car park a few minutes away, where you have to have around 10€ per day; at least the car is save then (it seems that cars get stolen occaionsly)
Roberto was really nice and gave us some hints about what we should care about and what we can do. He was really sorry that we had so bad wheather during our stay (that was the only annoying thing, that wheather was really bad)
So, in total I would really recommend this appartment!
