Location was very good for us as we traveled by train quite a lot. A bottle of wine and snacks were nice. Good WiFi.
However, the only comfortable bed for sleeping is the double one. We (4 persons) stayed a week there and for some of us sleeping was a challenge as well as the noise from streets during nights.
The house is old and some amenities (e.g. shower) could be more comfy.
For budget travelers and those who would like to feel true Catanian spirit it would be a good choice.
