The safer place in South America, tehre are a lot to see in a very short distance : possibility to go to the mountain, the beaches, see cultural things, the food is gorgeous with unusual sea food.
Inhabitants can be very nice and gelpful but Chileans do not have a service culture which is really a weakness and can be highly disappointing in some hotels. With taxis it is the same : if you find a good one he will be nice and talk to you a lot, otherwise he'll try to take your money by not adjusting the meter and taking the longest way as possible, be careful.
This city is not tourist friendly as its hard to find any tourist souvenirs and hard for non-Spanish speakers to navigate around with most locals hardly speaking or understand English.
Nice pit stop city. Most activities are outside of Santiago. The city is a bit polluted and if you have respiratory issue then travel gently.
The locals are super friendly and accommodating and generally you feel very safe walking around the city. Wouldn't need more than 3 days in the city.
You Must do the Touristic Bus Tour around the city, you can get off and on the bus all day, or do a round trip in 3 hours
a well organized country with good road infrastructure within the city and yet can be caught in traffic jam.
safe to move around in Providencia area. metro is clean and efficient even during peak period (~ 6 pm to 7pm). Taxi fare is rather affordable but shopping in big malls is rather expensive. police on foot patrol gives a good sense of security and feeling of safe to walk around even about 9pm or so.
