To many people, Santorini is a romantic place, a honeymoon destination and a place where everyone should visit once in a lifetime.
It lives up to expectations in terms of the scenery, but the experience I had wasn't totally pleasant.
When my friends and I arrived at Fira, Santorini by ferry from Mykonos, we were famished. We ordered lobster pasta and salad in a restaurant which promised to give us good discount. When our bill came, it wasn't correct. In fact, I observed the other table had problem with their bill as well. Either the waiters were poor at Mathematics or they were out to con us. You might want to have lobster pasta elsewhere in Greece but not in Santorini.
On our first night at Santorini, we walked along the streets of Fira. Unfortunately, my friend's mobile phone was pickpocketed from her backpack. There was no CCTV and there was no chance to getting the phone back. Although Greece felt safer than Italy, it is Europe afterall. Backpacks, especially those without zip, are strongly discouraged because they make you an easy target for pickpockets.
We sought help from the receptionist of our apartment. Initially, he advised that only 1 or 2 of us go to the police station to file the police report (there were 3 of us) because taxis apparently charge by person in Santorini. This makes no sense at all! In the end, the receptionist arranged for someone to drive us to the police station free of charge.
After my friend filed the police report, we asked the police to help us with transportation back to our apartment. A guy came in a vehicle (not police car), not taxi, drove for around 5 min, dropped us along the main road (which we had to walk for a few hundred metres) and charged us 15 Eur. This was exorbitant!
So you can see, my first impression of Santorini wasn't exactly great.
