We are staying in the Hotel Liberty in October for 7 nights and plan to do day trips from there to Taormina, Etna etc. the hotel gets great reviews and ratings but have only just noticed the comments about the street and area it is in being "squalid". Wondering if we have made the wrong decision and should have based ourselves in a town rather than a city. Any comments/advice? Is it safe to walk in the evenings in Catania?
