The apartment is in a residential quiet area, and it's located nearby the metro and the train station. There're several coffee places and restaurants nearby, so it's very convenient to get anything if you're not in the mood of going to Palermo to eat. The host, Alejandra, was very polite and helpful and gave me some recommendations when I arrived.
The only thing I didn't like about the place was the constant noise from the fridge and the fan in the bathroom. In addition, I was reminded about the check-out rules several times from day one and onwards (around 5 times) - I stayed for 6 nights and it felt strange to keep on receiving reminders from the host right after my first night like what time I have to leave and that I need to throw the garbage away (including getting this message at 7 am on my last day).
