The Airbnb itself is fine, the small balcony and air conditioning is definitely a plus on hot days. Another plus is a fact that it is close to center and train station so it is easy to go on trips.
However, the neighbourhood of the airbnb is not the best, San Berillo used to be one of the most dangerous areas and it looks like some of its history is still present. There is a lot of trash in the area, and some of the streets leading to the apartment dont have lights on during the night, which felt unsafe. Also be aware that the stairway leadign to the apartment is really steep so it might be a bit of a trouble if you have large luggage.
