I have never experienced service on this level, not even in a hotel. One example: When we met Paul who showed us the apartment, I realized that I forgot my phone in the taxi. Not only did he try to track the taxi, but when I connected my computer to track my phone, he jumped on his bike and tried to catch the taxi. This went on for 25 minutes, with me directing Paul over the phone. Eventually he got my phone back.
They also answered all our calls and handled all our questions right away. It was a world class service.
