I had a GREAT time at Martina's place!
Location:
just a few steps to the main street, walking distance from most attractions. There's plenty of bars and restaurants 1-2 minutes walking. There's also a small supermarket further down the road. Not big, but has all the essentials you may need.
Apartment:
The place is big, with a nice kitchen, a fully working shower, washing machine, living room. Upstairs you have the bed. It lacks natural light, but for me it was not a big deal.
The place was sparkling clean. You can hear some noise from nearby bars but it was not too loud. I'm a light sleeper and didn't have any problem. Unfortunately that's the price to pay if you want to stay in Catania city centre.
Host:
Martina was super nice and friendly, flexible with my check in times, and was constantly in touch. Whenever I asked some questions, she replied within a few minutes.
All in all I had a great time and next time I'll be in Catania I'll stay again at Martina's
