This was amazing. Email communication was great, the person who met us upon arrival was extremely welcoming and professional. He gave us a tour of the apartment and carefully explained everything. He was very patient and answered all of our questions. The company is available by phone all of the time and it was nice that everyone spoke English since my Spanish is very basic. I called them to reschedule my friend's car to the airport from 7:30 pm to 7 pm and they did so without a problem. My flight was delayed 3 hours and I called the company to book an additional car for me. They not only booked the car but let me stay in the apartment without being charged because no one else was renting the space the next day.
The apartment itself is incredibly relaxing. The decor is nice, the space is sparkling clean, the sunlight is wonderful and the pool area is very nicely maintained and heated. You can even rent a private whirlpool room by the hour.
If I return to Palermo, I will be using Ralf and his company.
