The place is fantastic and well appointed. The location is absolutely wonderful. Super walkable to restaurants, cafes, shopping and hip wine bars. It's super close to the bustling part of Palermo, but a few blocks away so it's not super busy or loud at the location. Except for construction at this time.
There is a building under construction, which will go on for months longer. If you need to sleep in past 8:30AM and or spend your day working in the apartment until 5-6PM, you may want to wait until the construction is complete to book this place. If your schedule works around that and or you have really good ear plugs and don't mind some background noise it's probably fine.
