Aldo is an excellent host. He excels in all categories:
Prompt communicator
Excellent advisor re local services and restaurants
Detailed instructions re driving into Palermo city center (not for the meek!)
The apartment is perfectly situated for walking to all the most interesting sites in all 4 quarters of the city. Great snack bars and restaurants abound, including in the apartment complex!
We took a bike tour (social bike Palermo) and their office is 7 minute walk from apartment. Highly recommended!
We also went rock climbing around Mt. Pellegrino (we are traveling with a rental car). Decent climbing so near an urban center.
In conclusion: stay here!
